And did direct two episodes of the show: one in Season 8 and one in Season 9.42.
When Haley gets pregnant in Season 8, Lenz was pregnant in real life. Schwahn makes a cameo in two episodes as Max, the record store owner.44.
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.
Haley has a huge arc surrounding her singing chops because Schwahn overheard Lenz singing in a parking lot and decided to give her character a singing career. Just like their characters, Lenz joined Tyler Hilton (Chris Keller) on tour. The court where the Tree Hill basketball games were shot is the same one Michael Jordan played on when he was in school, proving legends really are born in the Tree Hill High gym.19.
Paul Johansson (Dan) was a great basketball player when he was young.20.
The episode was really filmed in Honey Grove after the town won a contest in which fans wrote in, saying why One Tree Hill should come to their city.
All of the extras in the episode are kids from the town.33.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.The show title comes from the U2 song "One Tree Hill" from the Joshua Tree album. One Tree Hill was originally set in Illinois, but The WB asked Schwahn to set it in a warmer climate, which is how the show ended up taking place in North Carolina.5.Schwahn wanted Chad Michael Murray to play Nathan, but Murray wanted to play Lucas, so the producers agreed to cast him in that role.6.But going into Season 5, Schwahn decided he wanted to actually incorporate the idea.35.
