And did direct two episodes of the show: one in Season 8 and one in Season 9.42.
Schwahn was inspired to write the school-shooting episode (Season 3, Episode 16) after hearing someone talk about Columbine and whispering the name.One Tree Hill uncharacteristically jumped ahead four years to bypass college so the actors would play their own ages.34.Nanny Carrie (Torrey De Vitto) going crazy was originally just a joke Mike Daniels threw out in the writers room. Creator Mark Schwahn originally wrote One Tree Hill as a feature-length project called Ravens.2.Executive producers Brian Robbins, Mike Tollin, and Joe Davola spent four years convincing Schwahn to turn the movie into a TV series.3.In the 100th episode, Peyton stands up in the middle of Lucas' wedding and tells him she's still in love with him. Front Street, which housed Karen's Cafe and Clothes Over Bros, is currently a fully functioning coffee shop called Port City Java.39.During a take, Burton forgot her line and Brundage recited it back to her! One Tree Hill was shot in Wilmington, North Carolina, and you can visit a lot of the shooting locations still today. And the River Court was really outside along the river, but was dismantled after the show wrapped.40.Moira Kelly (Karen) found out she was pregnant after the pilot was shot, but Schwahn didn't want to write the pregnancy into the show, so they used an array of props to hide her belly. Though Jackson Brundage was only 6 when he was cast as Jamie, he was really good at memorizing lines. When Jamie was first written into the show, a lot of his scenes were dictated by what Brundage wanted to do.He would tell Schwahn he wanted to eat ice cream, and in nearly every scene, he'd be eating ice cream.Then, he'd want to play with Antwon Tanner, who played Antwon "Skills" Taylor, so Schwahn wrote storylines for them.11.Tanner read his lines only in the pilot, so after it aired, he called Schwahn up and said, "I didn't know [Nathan and Lucas] were brothers! To separate her from co-star Hilarie Burton (Peyton), Bethany Joy Lenz (Haley) was told she had to dye her blonde curls before starting to shoot One Tree Hill.13.
