Series creator and showrunner Mark Schwahn was later accused of sexual harassment while working on One Tree Hill.
Chad Michael Murray's co-stars say he "didn’t have anything to lose" as "number one on the call sheet."
"At that time, I said, ‘No I don’t want to do this,' and I was told I had to," Lenz's costar Sophia Bush recalled.
The allegations come after the cast and crew of One Tree Hill accused Schwahn of sexual harassment.
The Royals star Alexandra Park came forward with allegations against Schwahn, prompting E! to suspend the showrunner.
