Ben was leaving the 'Late Show' studio Thursday night where he was promoting his new flick, "Justice League." Everything seemed fine and dandy ... until Colbert brought up Harvey Weinstein.
Seems the subject threw off Ben, who then got grilled about his own sexual misconduct. You'll recall Ben apologized for apparently groping a former MTV host in 2003. Another video surfaced showing him in 2004 getting handsy with a Canadian TV host.
