When One Tree Hill premiered on the WB in 2003, it was seen as the successor to Dawson’s Creek, which launched the careers of so many young actors. One Tree Hill did the same.

The series filmed in and around Wilmington, North Carolina, like Dawson’s Creek before it. It featured the fictional small town of Tree Hill, centering on Tree Hill High School and the rivalry between two half-brothers who vied for the same spot on their basketball team. The rivalry between Nathan (James Lafferty) and Lucas (Chad Michael Murray) eventually quelled and the story expanded to their friends and found family.

Moving from high school to post-college days with a four year time jump, the series was able to capture the feelings of isolation teens experience while growing up, and then uncertainty adults face when first navigating the world on their own. The show also featured a ton of now familiar faces as the result of that long run.

While many up and coming actors appeared in the early days of the show, the later seasons of One Tree Hill brought in plenty of new faces to replace those who left the show behind. Some of those new faces are the most recognizable from One Tree Hill’s nine seasons on the air. 

Here are the 15 Famous Actor You Forgot Appeared On One Tree Hill.

15. Candice Patton

Before she helped save the lives of superheroes, Candice Patton guest starred all over TV, and one of those roles was a young woman named Tanesha on One Tree Hill.

Tanesha only appeared in two episodes while Patton was busy auditioning for bigger roles. She was the roommate of Amanda Schull’s character Katie, who went on to stalk and attempt to kill a pair of main characters in later seasons.

Patton followed up One Tree Hill with episodes of Grey’s Anatomy, CSI: Miami, and The Game.

These days, Candice Patton anchors a team of superheroes in The Flash as reporter Iris West. The character is more than just a love interest as she’s often the emotional center of the group, integral to unraveling the show’s mysteries, and always willing to pursue a problem on her own.

14. Jana Kramer

When Jana Kramer joined the cast of One Tree Hill, her character blew through small town as an actress with quite a few skeletons in her closet.

Kramer debuted as Alex Dupre in the seventh season of the show as a way to shake things up. Alex was a bit of a schemer with a dark past, but all she really wanted was to be successful.

She worked as an actress and a model when originally introduced before trying her hand at penning her own movie script and launching a career as a country singer.

Art imitates life for Kramer. Though she does still audition for roles here and there, Kramer’s primary focus has become her country music career. Since the end of One Tree Hill, she’s released two full length albums and an EP as well as made it to the finals on Dancing With The Stars.

13. James Van Der Beek

In a funny twist, James Van Der Beek returned to the area that made him a household name for One Tree Hill. The series filmed in the same area as Van Der Beek’s Dawson’s Creek.

Van Der Beek played a tyrannical director interested in turning Lucas Scott’s novel into a movie. It was a fitting role for someone who played budding film student Dawson Leery in the same location.

Van Der Beek hasn’t found the huge movie success the spotlight of Dawson’s Creek might have suggested, but he became a television staple.

In addition to frequent guest arcs across TV, he also played a satirical version of himself in Don’t Trust the B- in Apartment 23 and a Power Ranger in a short film. Recently, he also took on the role of musician Diplo for a spoof.

12. Ashley Rickards

Before things got Awkward. for Ashley Rickards, she played a high school student at Tree Hill High looking for a place to belong.

Rickards appeared in season six of One Tree Hill after the series made its time jump. She was a fifteen-year-old in the foster system named Sam who shoplifted from Brooke’s store.

Brooke ended up taking the young woman in. Sam opened up a dialogue about adoption for Brooke, who wanted to start a family, and even thought of her foster mother as her “first mom.” Sam left the series when she decided to give a relationship with her biological mother a shot.

Since One Tree Hill, Rickards took the lead in MTV’s Awkward., appeared in American Horror Story, and recently guest starred on The Flash. Rickards also tried her hand at directing, stepping behind the camera for two episodes of Awkward.

Most people don’t know Kate Voegele for her acting chops since much of her career has been devoted to music, but she spent four seasons recurring on One Tree Hill.

Voegele began acting as aspiring singer Mia on One Tree Hill not long after her first full length album dropped. In a bit of synergy for the show that prided itself on discovering new artists, Mia worked on an album while Voegele worked on her second. Music that made it into her second album also appeared in the show.

Voegele’s most recent release is a single called Shoot This Arrow. The song addresses harassment in the wake of One Tree Hill’s showrunner Mark Schwahn being accused of inappropriate behavior by actresses and writers who worked with him.

Since working on One Tree Hill, Voegele has been focusing on music full time.

Britt appeared for the first time on the show early in season one as a referee. In season six, he returned as a rival for Nathan, and someone who wanted to make it as a pro. His appearance was brief as he was initially kicked off his basketball team before heading to a European team.

Britt has become one of the most prolific television actors. In addition to a stint on Agents of S.H.I.E.L.D., he also appeared in The Vampire Diaries, Nikita, and Grimm. He also filmed pilots for Wonder Woman and Behind Enemy Lines.

Torrey Devitto’s arc on the series involved an obsession with the Scott family, kidnapping their kid, and regularly wielding a knife. She was one of the show’s most interesting villains, and it wasn’t her only stop for teen dramas.

Since the show, Devitto made a slew of series appearances for both the CW and Freeform, most memorably as big sister Melissa Hastings on Pretty Little Liars and a doctor using vampire blood as a treatment on The Vampire Diaries.

Sylvia Baker entered as an antagonist for Brooke, not seeing eye to eye with her future daughter-in-law. Accused of coddling her son too much, Sylvia was quick to lash out. She and Brooke eventually bonded though, and she even befriended Brooke’s own mother.

Before he landed his One Tree Hill role, Lachey appeared in several episodes of Charmed on the WB and even landed spots in a few movies. For One Tree Hill though, he nabbed a pretty familiar role– himself. Lachey wasn’t on the show to perform, but instead as someone interested in purchasing a song.

Following his episodes of the show, Lachey guest starred in a few other series and tried his hand at a solo music career. Hosting gigs and reality TV seem to be his bread and butter though. He even competed on Dancing With The Stars.

Following One Tree Hill, he actually reunited (briefly) with Ashley Rickards in American Horror Story. In season one, she was one of his characters’ victims.

Swanson appeared in the episode “Don’t You Forget About Me,” which homaged the legacy of Hughes. The episode provided nods to many of his famous films. Swanson played a woman who gave Nathan a ride back to Tree Hill after being stranded in the woods.

Manganiello already played Flash Thompson in a Spider-Man movie before he landed a recurring role on One Tree Hill. A household name now, fans might not remember he was once a Tree Hill bartender.

Manganiello recurred as Owen, a man who caught Brooke’s eye. The two dated for a string of episodes, but Brooke’s desire to start a family conflicted with his own desires, and they parted ways.

Of course, the actor has come a long way since his bartender days. He’s stripped in Magic Mike, lived in a town of vampires in True Blood, voiced a Smurf, and become another comic book character.

Manganiello recently became the DC Extended Universe’s live action version of Deathstroke. He’s rumored to be appearing in several upcoming films for the DCEU along with the character’ solo film.
