On the special edition DVD actors commentary track, the actors playing Krug and Weasel boast about how they terrorized the actresses playing Mari and Phyllis, right down to hinting during the filming of the rape scene that they'd go ahead and actually commit the act if they didn't think the actresses' performances were convincing enough. They seem to think this is awesome.
...and David Hess complained that he couldn't ride the subway anymore, for the dirty looks he was getting. No wonder.
The part where they make Phyllis pee her pants? For real.
