The filmmaker has been one of the most vocal opponents of The Cosby Show star, who has been accused of inappropriate behaviour and rape by more than 30 women over the past 10 months.

To make matters worse for Cosby, his deposition in a 2005 court case was released last week (ends12Jul15), in which he admitted obtaining multiple prescriptions for the powerful sedative Quaaludes to give to women he wanted to have sex with.

In a new interview with Rolling Stone magazine, Apatow continues his quest for the truth, revealing that a driving factor in his passionate war against Cosby is that he has a "personal connection" to the case.

Apatow confesses, "The Cosby thing I took seriously because I know one of the victims, who is not going to come forward. I had a personal connection to it, where somebody that I care about said that's exactly how it went down."

The producer urged others to come forward, adding, "If women don't speak up, more women will be raped. So it's really all about preventing other people from getting hurt, because Cosby's on tour - ignoring all of the victims is a signal to other victims that when you speak up, people will not take care of you and do something about it."
