It’s a testament to the difficulty of acting that sometimes the best of friends must play the bitterest of enemies. For example, look at Patrick Stewart and Ian Mckellen (and try not to squee too loudly).

On the flipside, sometimes two actors whose chemistry couldn’t be more combustible and full of loathing have to appear on screen together as not just best friends, but loving siblings. Siblings who would walk through fire for each other, even if they’d rather be pushing their opposite number into one and watching them burn with glee.

Not all of the entries on this list are quite so malicious. However, you have to wonder how some of these pairings didn’t end up with one occupant thrown lifeless into a ditch at some point or another, as the tension continued to build on set.

From the glitz and glamor of old Hollywood to the tween Disney idols of the new millennium, sometimes you just end up unlucky with your fated co-star and are forced to make nice. Or, as it turns out, sometimes you load yourself down with rocks when they try to drag you away in an attempt to make them wrench their back.

Here are the 15 On-Screen Siblings Who Actually HATED Each Other.

15. Tom Hardy and Shia Labeouf – Lawless

You’d be hard-pressed to find two more intense and dedicated actors working today, so naturally when Tom Hardy and Shia Labeouf worked together as brothers on the 1930’s bootlegging drama Lawless, the situation was combustible.

Shia Labeouf’s been no stranger to controversy and questions about his behavior and mental health have begun to pop up in the past few years after several incidents involving arrests for public intoxication and throwing punches in the streets.

This physicality apparently came out on the set of Lawless, with director John Hillecoat confirming that Labeouf and Hardy came to blows on-set to the point that they had to be restrained by crewmembers around them. Though Tom Hardy himself has said he was knocked out by Shia, the director has maintained that that was an exaggeration, and it is hard to see how Labeouf could have taken down the much more muscular Hardy with a single blow.

14. Michael C. Hall and Jennifer Carpenter – Dexter

There’s “whirlwind romance” and then they’re “dating, getting married, and divorcing all during the production of a TV show you both star on.” Jennifer Carpenter played the detective sister of the main character on Showtime’s serial killer drama Dexter. 

The show centers on the titular killer, who balances a double life as a forensic expert with the Miami Metro Police Department while also moonlighting as a serial killer who hunts his own kind using evidence gleaned on the job.

Jennifer Carpenter and Michael C. Hall began dating in 2007, and eloped in 2008. However, citing irreconcilable differences, the two petitioned for divorce in 2010 after just two years, already admitting to have been separated and dating other people.

13. Nikki Reed and Robert Pattinson – Twilight Movies

Twilight Cullen Family 15 On Screen Siblings Who Actually HATED Each Other

It’s become overwhelmingly clear that almost nobody in the Twilight movies had much love for the franchise, with Robert Pattinson and Kristen Stewart being particularly vocal about their dislike of their most successful film project.

In fact, the only person who seemed to have fun was Michael Sheen, who played the elder vampire Aro and gleefully chewed the scenery like he thought there was blood in the walls.

Nikki Reed, who played the sister of Pattinson’s character, has been critical of her co-stars’ disinterest, in particular biting into the main stars over a perceived shift in their attitudes during production, saying that “…success comes along and changes the dynamic. We’re not all best friends, and we’re not all going to hang out together after the final movie is done.”

12. Eric Roberts and Julia Roberts – Blood Red

The first in a trifecta of actual siblings who also played siblings and hated each other, Julia Roberts made her screen debut in the Western period drama Blood Red, co-starring her brother Eric Roberts.

Eric’s career has had some high highs and low lows, going from critical acclaim in Runaway Train to a role in A Talking Cat!?!. (The fact that those exclamation points and question mark are actually in the official title should tell you everything you need to know about the movie’s quality.)

The relationship between the Roberts siblings has been just as contentious; eventually getting so bad that Julia sided against her own brother during custody hearings with his ex-wife for their daughter Emma Roberts, now an actress herself.

Cited in particular was Robert’s ramped-up drug use and violent brushes with the law. At least recently, it seems that the Roberts siblings have buried the hatchet and reconciled in the wake of the birth Julia Roberts’ twins.

11. Elle Fanning and Dakota Fanning – My Neighbor Totoro (English Dub)

As child actors, the Fanning sisters delighted audiences and achieved early critical and commercial success, with Dakota being nominated for a Screen Actor’s Guild award at the young age of eight for her role in I Am Sam, following it up with work in War of the Worlds and The Runaways, while her sister had a career beginning with a break-out role in Super 8 and more recent turns in Maleficent and The Neon Demon.

So far, they’ve refused to share the spotlight, only co-starring in a few productions including the Disney English dub of the classic Studio Ghibli animated film My Neighbor Totoro as “…something of a peace treaty…”

They’ve set up shop literally on opposite ends of the country, and appear to be growing up to be a study in contrasts. Allegedly, Elle gets Los Angeles to herself, apparently being much more enamored than her sister with Hollywood glitz and glamor, while Dakota has laid claim to New York. Though things have calmed down between the two a lot recently.

10. The Jonas Brothers – Camp Rock

The Jonas Bros Nick Joe Kevin 15 On Screen Siblings Who Actually HATED Each Other

The halcyon days of the Jonas Brothers performing as a trio seem so far away now, but at one point they were inseparable, starring in the Disney Channel original Camp Rock and headlining massive tours and concert films across the country. Fans were heartbroken when the group split up in 2013, which was apparently due to consistent infighting amongst the brothers.

Nick Jonas has since admitted that he finally took the other brothers aside and broached the topic of splitting up since no one’s issues were being addressed, likening the arrangement to a train about to derail.

Though the brothers remain apart, at least their personal relationships have repaired over the years. Additionally, each former member has enjoyed individual success in music and entertainment since.

9. Topher Grace and Lisa Robyn Kelly – That 70’s Show

That 70s Show Topher Grace Lisa Robyn Kelly 15 On Screen Siblings Who Actually HATED Each Other

There was apparently a great deal of bad blood behind the scenes of That 70’s Show set in 1976 Wisconsin, with substance abuse, resentment among the cast, and the departures of the two biggest stars, Topher Grace and Ashton Kutcher, before the series finales.

Rumor had it that Topher Grace disliked the show’s shifting focus away from his character and onto the surrounding players outside of the Forman family, and thus he resented the rest of the young members of the cast.

Not helping was the spiraling substance abuse problems of Lisa Robyn Kelly, who played Topher Grace’s older sister Laurie Forman. A tragic miscarriage and burgeoning alcoholism led to her leaving the show in 2003, and though she returned for a brief stint in season 5, it didn’t take. She sadly died in rehab in 2013.

8. Shannen Doherty and Alyssa Milano – Charmed

Charmed show cast 15 On Screen Siblings Who Actually HATED Each Other

Whatever acting abilities or charisma Shannen Doherty has, they’ve been eclipsed in the minds of public by the stories of her being a calamitously difficult actress to deal with on set. You have to really scour the internet with a fine-toothed comb to find a set where people haven’t complained about her diva behavior and fights with co-stars, and her brief stint on Charmed was no different.

Alyssa Milano has gone on record in recent years saying that the set was “like high school,” and reports at the time suggested that Doherty was eventually fired after Alyssa Milano provided the producers of Charmed with an ultimatum: either she or Doherty could stay, but not both.

Regardless of the actual reason for Doherty’s dismissal after 3 seasons, it’s clear that, as with Beverly Hills 90210, her departure didn’t hurt the show, and Charmed went on to five more seasons with Rose McGowan replacing Doherty.

7. Jake T. Austin and Selena Gomez – Wizards of Waverly Place

Jake T. Austin and Selena Gomez 15 On Screen Siblings Who Actually HATED Each Other

Selena Gomez first graduated to a starring role as one of a trio of magical siblings on the Disney Channel hit Wizards of Waverly Place. She starring alongside Jake T. Austin and David Henrie as their sister Alex Russo, as part of a wizarding family living in Manhattan and competing to become the Family Wizard of their generation. It seemed as if some competitiveness bled into real life, though, as Selena Gomez’s part on on the show grew along with her fame and fortune.

When she decided to quit Waverly Place in 2013, Austin was not happy, hitting back at his co-star’s desire to move onto more bigger, more adult things with a snippy tweet reading, “When an artist’s definition of ‘growing with their fans’ is creating content they aren’t even allowed to see…” Luckily, it seems to be jealousy born of youth, as the two have reconciled since, and Jake recently sent Selena a heartwarming message of support after the latter’s kidney surgery.

6. Ashley Tisdale and Lucas Grabeel – High School Musical

High School Musical Lucas Grabeel and Ashley Tisdale 15 On Screen Siblings Who Actually HATED Each Other

For whatever reason, Ashley Tisdale and Lucas Grabeel were not all in this together as the scheming Evans siblings in the High School Musical trilogy. Though the two were inseparable on-screen as Sharpay and Ryan, and have since reunited in-character for other performances, they apparently hated each other back during the filming of the first High School Musical.

According to Tisdale, at the beginning of production “We were not close. We were not good friends, lets be honest. We hated each other, I’m not kidding.” She attributed it to being in character, but whatever the reason, at least they’ve gone on to become friends since, and by the time they wrapped up production, she saw him as a brother.

5. Tracey Gold and Kirk Cameron – Growing Pains

Growing Pains cast 15 On Screen Siblings Who Actually HATED Each Other

Kirk Cameron was the breakout star of Growing Pains, not for lack of trying to sabotage his own career with increasingly dictatorial on-set demands, including firing actress Julie McCollough and writing out her character because she posed for Playboy.

As the golden child on set, his demands were met despite increasing frustration from his co-stars. Tracey Gold, who played his sister Carol Anne Seaver, began struggling with an eating disorder and an obsession with her weight, which was exacerbated by the cruel jokes her on-screen siblings made about her, despite the fact that she dropped from 133 pounds to an almost skeletal 80. (It’s no wonder Kirk Cameron wasn’t invited to her wedding in 1994.)

In the years, she seemed to be chummy again with Kirk during a reunion special in 2000, and despite a brief twitter “feud” in 2016 over support for the LGBTQ community, the two seemed to have reconciled since.

4. Damn Near All The Brady Girls – The Brady Bunch

The Brady Bunch Jan Marcia Cindy Mike Greg 15 On Screen Siblings Who Actually HATED Each Other

The Brady Bunch and its cast projected a wholesome image as an all-American family weathering the trials and tribulations of growing up. Behind the scenes was very different, however, with a veritable love dodecahedron that set the stage for rivalry, betrayal, and cocaine abuse amongst the on-screen Brady siblings.

As puberty began to hit the girls, affections shifted, sparking rivalries and bitter resentment from Cindy Brady’s actress Susan Olsen as Jan’s actress Eve Plumb began “developing.”

While some of the TV siblings seem to have moved on with the help of decades of hindsight, Maureen McCormick, who played Marcia Brady and Eve Plumb (who were also apparently off-screen lovers), scuttled a 2010 reunion on The Today Show after refusing to appear together.

3. Balthazar Getty and Everybody Else – Brothers and Sisters

Brother and Sisters season 3 15 On Screen Siblings Who Actually HATED Each Other

Hell hath no fury like a woman scorned, but only slightly below that on the fury scale are that woman’s friends, especially if you’ve turned them all against you. Such was the fate of Balthazar Getty, who became loathed by the other actors on Brothers and Sisters after a highly publicized affair with Sienna Miller.

In addition to many of his co-workers simply liking his wife Rosetta more, the mood on set grew cold as Getty’s behavior became increasingly hostile and erratic, with reports of him showing up late to set and in such foul moods that he reduced crew members to tears, even though he was known to forget his lines.

Although he has since reconciled with his wife following a separation, the same can’t be said for his relationship with his TV brethren.

2. Humphrey Bogart and William Holden – Sabrina

Humphrey Bogart Audrey Hepburn William Holden Sabrina Billy Wilder 15 On Screen Siblings Who Actually HATED Each Other

You can’t make your opinion of someone much clearer than William Holden did with Humphrey Bogart, as he came right out and stated, “I hated that bastard … he was always stirring things up when he didn’t have to” according to Gene Philip’s Some Like It Wilder: The Life and Controversial Films of Billy Wilder. 

The two co-starred as brothers in the original Alfred Hitchcock version of Sabrina, and the set atmosphere was not helped by the fact that the two legendary actors were also legendary boozehounds, with Holden’s drinking problem in particular having worsened since the days of Sunset Boulevard.

For his own part, Holden apparently irritated Bogart with constant smoking, and Bogart suspected the actor of trying to make him cough while saying his lines, seething to director Billy Wilder, “I want this sabotage ended, Mr. Wilder.”

1. Bette Davis and Joan Crawford – Whatever Happened to Baby Jane

Bette Davis Joan Crawford On Set Whatever Happened Baby Jane 15 On Screen Siblings Who Actually HATED Each Other

Betty Davis and Joan Crawford is the celebrity rivalry to end all rivalries, and the only entry on this list vicious and famous enough to get a limited TV series made based on it– Ryan Murphy’s Feud.

Davis and Crawford were lifelong professional and personal rivals, but by the time they were cast in Whatever Happened to Baby Jane, their careers were on the wane. It was a decidedly meta casting decision, with the two playing acting sisters whose pop culture relevancy had reversed, much to the seething jealousy of Davis’ character.

The legendary on-set antics ranged from passive-aggressive notes to the installation of a Coca-Cola vending machine on the insistence of Bette Davis (Joan Crawford’s husband was the chairman of Pepsi at the time) to more nasty stories of Davis kicking Crawford in the head and Crawford filling her pockets with rocks for a scene where Davis had to drag her paraplegic character.

They all culminated in Bette Davis being nominated for the Academy Award for Best Actress, and Joan Crawford being so upset at not being nominated that she offered to accept the award for any of the other nominees in the category should they not be able to attend.

Do you know of any other acting pairs who played on-screen siblings and hated each other’s guts off? Let us know in the comments.
