The actor appeared on the late-night show to promote Justice League but conversation soon turned to more serious matters.

“This is a comedy show, right?” he laughed, when Colbert brought up Weinstein and their collaboration on movies like Good Will Hunting, Shakespeare In Love and Chasing Amy.

“It was awful to see the extent of these terrible crimes, and it was hideous,” he said, referring to the claims made against the movie mogul in recent weeks.

Affleck said the movies they had made together felt “tainted” when you realise that “while we were making these movies and having these experiences, there were people who were suffering and dealing with awful experiences.”

Colbert also asked him about an incident in which Affleck was accused of groping an MTV presenter in 2001.

“I don’t remember it, but I absolutely apologized for it. I certainly don’t think she’s lying or making it up. It’s just the kind of thing that we have to as men, I think, as we become more aware of this, be really, really mindful of our behavior and hold ourselves accountable and say, ‘If I was ever part of the problem, I want to change,” he said.

The pair begin to discuss the allegations at the 2.34 minute mark and it makes for tense viewing at times. Check it out here:
