Check Out 9 Facts Even the Biggest ‘One Tree Hill’ Fans Probably Don’t Know

Sophia Bush had to audition three times for the role of Brooke Davis because she was told she did not appear sexy enough, but then looked too sexy.

The show was originally set to take place in Illinois, but The WB wanted the series set in a warmer climate; therefore, North Carolina became the permanent residence for the characters.

Mark Schwahn — the creator — originally wanted Chad Michael Murray to play the role of Nathan (WTF?!). Fortunately, Chad wanted the part of Lucas Scott.

Well — we certainly can't imagine him as any other character!

To differentiate Hilarie Burton (Peyton Sawyer) and Bethany Joy Lenz (Haley James Scott), Bethany had to dye her hair before they started shooting.

Attention all OTH fans: You can still access Peyton’s website, Punk & Disorderly, online!

The series jumped ahead four years to skip the college years so the actors would finally play their real ages.

Austin Nichols and Sophia Bush’s onscreen characters (Julian and Brooke) had such great chemistry because the two were dating in real life.

In season 8, Haley James Scott gets pregnant, which worked out because Bethany Joy Lenz was actually expecting a baby.

Mark Schwahn wrote the school shooting (Season 3, Episode 16) after hearing someone mention Columbine in a whisper.

He felt this tragic event should be talked about out loud.
