Most people can probably name their favorite actor off the top of their heads, and most can probably also name their favorite role by that actor. It is an actor's job to give the best performance they can in a film, and many incredible performances have captured audiences' hearts over the years.

But sometimes, an actor can do such a great job in their role that people overlook their costars who are giving just as great a performance. These unsung actors helped make their movies great, but sadly don't get nearly as much credit.

Tom Hardy - The Revenant

Tom Hardy's career has exploded in recent years, and he's been starring in everything from indy projects to blockbuster action franchises. His Oscar-nominated performance in The Revenant, however, has been mostly overshadowed by the role that finally won Leonardo DiCaprio his first Academy Award.

While DiCaprio certainly earned his Oscar, Hardy's villainous turn as John Fitzgerald was just as impressive. Dripping with menace and savagery, Hardy physically and psychologically sinks into his role just as DiCaprio does, and turns in a truly unsettling performance that deserves more recognition.

Geoffrey Rush - Pirates Of The Caribbean

Ask anyone what character they remember most from Pirates of the Caribbean and they will undoubtedly say Johnny Depp's lovable scoundrel, Jack Sparrow. However, many overlook the fantastically over-the-top performance by Geoffrey Rush as the franchise's first villain, Barbossa.

Rush makes Barbossa both cartoonishly fun and downright frightening, delivering witty one-liners one moment and lamenting his suffering under a terrible curse the next. The actor chews enough scenery to compete with even Depp's performance and makes Barbossa a delightfully complex villain.

Vincent D'Onofrio - Men In Black

Men In Black was a fun buddy comedy tied together by the hilarious chemistry of Will Smith and Tommy Lee Jones. Their witty, odd couple repartee made the film what it was.

What many people forget is the criminally underrated Vincent D'Onofrio's role as the film's antagonist. D'Onofrio somehow manages to convincingly portray an alien bug wearing a human body as a disguise, and commits so hard to the physicality of the role that it is easy to forget that he is, in fact, a real person. D'Onofrio is clearly having a blast as the man formerly known as Edgar and fills the screen with so much camp that he is easily one of the funniest parts of an already funny movie.

August Diehl - Inglorious Basterds

Christoph Waltz unquestionably stole the show in Quentin Tarantino's revisionist tale of World War II, outshining even the best of the ensemble cast. While Mélanie Laurent's fantastic performance in Inglourious Basterds also deserves far more attention, it is August Diehl who is truly overlooked.

Appearing for only one scene, Diehl pulls off almost as tense a performance as Waltz does in the opening. Diehl plays an SS officer who suspects Michael Fassbender and his comrades are not who they claim to be. His crafty but suave interrogation of them and his subtle expression when he finally trips Fassbender up is haunting, and easily makes his scene one of the film's best.

Ruby Rose - John Wick 2

The John Wick franchise reinvigorated Keanu Reeves's career, and his incredible stunt work has made the character one of the biggest action stars in the industry today. Many of his costars have not garnered the same amount of attention though, even though most all of them are fantastic.

Ruby Rose's Ares in John Wick 2 may be the most notable, as she performs not only some impressive stunt work when she goes toe to toe with Wick, but also provides excellent representation as an assassin who communicates only through ASL. Rose handles this superbly, and is an ever-present threat throughout the film, giving a performance that is both intimidating and thoroughly entertaining.

John Cazale - The Godfather: Part II

The Godfather: Part II is considered one of the greatest movies ever made, and every member of its ensemble cast turns in a stellar performance. Robert De Niro's seminal turn as young Vito Corleone has gone down as the film's most acclaimed, but Diane Keaton, Robert Duvall, and especially John Cazale also deserve far more praise.

Cazale plays Fredo Corleone, the middle child who is treated as the black sheep of the family. Cazale's Fredo is a tragic character, a good man who just wants to be respected like his brother and reluctantly betrays the family he thought has left him behind. Fredo's pain is portrayed fabulously by Cazale, and his breakdown at the end of the film is absolutely heart-wrenching.

Eli Wallach - The Good, The Bad, And The Ugly

Clint Eastwood's Man With No Name has become the template for all Wild West heroes since, with his rugged demeanor and effortless coolness. Often forgotten alongside Eastwood's titular "Good" is Eli Wallach's excellent turn as the film's "Ugly."

Wallach's character Tuco is arguably the heart of the film, contrasting Eastwood's strong silent type with a boisterous, treacherous foil. Wallach manages to be funny, despicable, and intimidating all at once, and keeps the film's stakes high as he makes it clear that he could turn on anyone at any time. Even alongside Eastwood's steely gaze, Wallach makes Tuco one of cinema's all-time greatest anti-heroes.

Ian McDiarmid - Star Wars: Return Of The Jedi

Every Star Wars villain has lived under the incredibly imposing shadow of Darth Vader. Even Emperor Palpatine, the true big bad of the saga, is often secondary to James Earl Jones and David Prowse's legendary dark lord. This is a shame because Ian McDiarmid's performance in the role is absolutely stunning.

Perfectly blending campiness and actual menace, McDiarmid enthusiastically disappears into the role. His Palpatine is larger than life and somehow is believable to be pulling the strings of the cultural icon that is Darth Vader. While Vader may always be the face of the franchise, Palpatine remains right there alongside him. It is no wonder that McDiarmid has reprised the role in all three trilogies.

Aaron Eckhart - The Dark Knight

Heath Ledger deserves all the praise in the world for giving his iconic portrayal of the Joker in The Dark Knight, and his turn in the role will forever be cemented in movie history. His performance is so good, in fact, that it caused Aaron Eckhart's phenomenal turn as Harvey Dent to fly almost under the radar. As Dent, Eckhart is charming, charismatic, and a great man among the chaos of Gotham City.

It is in Dent's fall from grace that Eckhart truly shines, though, and his transformation into Two-Face is tragically convincing. Showing both Dent's idealism and Two-Face's anger and suffering, Eckhart turns in one of the best incarnations of the character ever and could have easily carried his own movie, if given the chance.

Ted Levine - Silence Of The Lambs

Now that Hannibal Lecter has gone down as one of the best horror villains of the '90s, and arguably of all time, it is easy to forget that he is not the villain of Silence of the Lambs. That title belongs to Ted Levine's Buffalo Bill, in what may be the pinnacle of overshadowed performances. Levine fully transforms into the disturbed serial killer and gives a performance that is still haunting to this day.

There is an unnerving feeling of dread every time Bill is on screen, as he carries out his crimes with an eerie casual demeanor. Levine manages to make audiences feel strangely sorry for Buffalo Bill, yet at the same time, terrifying them enough to never look at lotion the same way again. Anthony Hopkins may have stolen the spotlight, but Levine helped to make the film the classic it is.
