History Trivia / OneTreeHill

** Chris Keller is implied to be older than the rest of the Tree Hill kids; Tyler Hilton is actually younger than all of the actors except for James Lafferty.

** Mark Schwahn (Series creator & showrunner) stated that the ending to episode 2x10, in which Lucas gives a speech about someone he cares about drifting away & then turns up at Brooke's house, didn't make any sense. He added that his actual intention was for Lucas' speech to be referred to Peyton (which in fact is what a viewer is supposed to think after hearing his words).

* It's worth noting that while James Lafferty was a downplayed example as listed above for the first four seasons, he actually became an aversion after the TimeSkip, as he was 22 when the fifth season premiered, the same exact age as Nathan.

** In the midst of the [=#MeToo=] movement, various female members of the cast and crew accused series creator Mark Schwahn of sexual harassment, with Creator/HilarieBurton later confirming that this was the reason she left the show after the sixth season. Chad's reason for departing at the same time has been speculated as him not being satisfied with his income, but given that almost every single male cast member has backed up the allegations against Mark, it's also possible he left in protest given his closeness with Hilarie.

** During the late 2017 Hollywood Sexual Harassment Scandal, the female members of the show's cast & crew accused series creator & showrunner Mark Schwahn of sexual harassment & assault, even going so far as to allege that it was an open secret in Hollywood about how toxic a work environment ''One Tree Hill'' was. Creator/HilarieBurton and Creator/DanneelAckles specifically cited the harassment they received as the reason they left the show, and the accusations were corroborated by not only ''every'' male cast member, but the cast & crew of ''Series/TheRoyals'', Schwahn's next project, as well. Schwahn was fired from that show after an internal investigation.

** The actual circumstances behind the departures of Creator/ChadMichaelMurray & Creator/HilarieBurton at the end of Season 6 weren't confirmed until November 2017, nearly a full decade after the fact. Amongst the rumors of both actors wanting more money, are rumors that one of the two was willing to return but the producers didn't want to keep one half of the pairing without the other. It was ultimately revealed in the midst of the Hollywood sexual harassment scandal in late 2017 that Hilarie chose not to renew her contract at the end of the sixth season due to sexual harassment she received from Mark Schwahn during her time on the show.

* IAmNotSpock: In one interview, Paul Johansson tells the story of one fan who hit him with her handbag because he was "so mean to that boy" and he had to explain to her that he was an actor and not Dan Scott.

** Creator/DanneelAckles was 26 when first cast as Rachel Gatina in the third season.

** All of the kids actors were subject to this, with James Lafferty being the youngest at 18 when production began on the series whilst Creator/ChadMichaelMurray, Creator/HilarieBurton, Creator/BethanyJoyLenz, Creator/SophiaBush & Creator/LeeNorris were all in their early twenties, Brett Claywell (Tim Smith) & Bryan Greenberg (Jake Jagielski) were in their mid-twenties, and Antwon Tanner (Skills) was 29, a full 11 years older than Lafferty & only 7 years younger than Creator/MoiraKelly, who was playing Lucas' mother. As the show took four seasons to narrate two years worth of story, the gap only widened & became more apparent. Part of the reason for the four-year jump was so the actors could play characters closer to their ages. While it showed with most of them sans Lafferty who was extremely close to his character's age to begin with, Lee Norris looked very convincing as Mouth, to the point that after the time skip he actually looked ''less'' believable as a character his own age than the others.
