Chad Michael Murray was the first actor to be cast in the show, though creator Mark Schwahn originally wanted him to play Nathan, having seen him in bad guy roles before. But Murray himself wanted to play Lucas, because he felt that the character had a back story he could connect more to, since he also experienced being abandoned as a child.
When talking about casting the role of Peyton, 'Mark Schwann (I)' said: "They asked why I wanted Hilarie Burton, and my answer was, 'She has a lot of pain in her eyes. And I want that pain in Peyton's eyes'. We always laugh about it, because Hilarie is like, 'It's a good thing a lot of crummy things happen to me in my life'."
Since the start of One Tree Hill, James Lafferty and the cast and crew of the show host a basketball game toward the end of every season to benefit different charities. Along with these charity games, One Tree Hill has also hosted the Hurricane Katrina Relief Softball Game and, toward the end of the second season, the show's members also hosted a charity football game. At all charity events, most of the cast and crew get split into two teams and play. The proceeds of each game have gone to different charities.
When Jamie was first written into the show, a lot of his scenes were dictated by what Jackson Brundage wanted to do. He would tell Mark 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.
The name "One Tree Hill" was taken from a U2 song of the same name. The creator, Mark Schwahn, was listening to 'U2''s 'The Joshua Tree' album. When the song "One Tree Hill" came on, he decided to make it the title. (The song itself is named after One Tree Hill, a volcanic cone in the city of Auckland, New Zealand's largest city. The tree was removed in 2000 after being attacked in 1994, however, a plaque exists there and the location is still known as One Tree Hill, or more recently, its Maori name: Maungakiekie.)
