Sure, as long as it's all clear up front. I get the impression from what I've heard about Max Hardcore in particular and the, um, male participants of that genre in general, that it's usually not a case of industry stars versed in the procedures agreeing to do really nasty stuff for a lot of money, but of amateur actresses showing up on the set and being attacked. A rape scene is a rape scene is a rape scene. Agreeing to get fucked on a porn set is not the same as giving total consent to be brutalized.
By the way, I've done some Googling and it appears I was thinking of Paul Little (aka Max Hardcore)'s obscenity conviction, which was a criminal trial, not a civil suit. My apologies for mixing those up. But check
these articles/blogs out. They're not the most objective sources, but the information in them is easily verified, and it's pretty horrifying. Some of these films lead to hospitalization and some other pretty awful physical and emotional consequences. This is rape on film, nothing less.
And I say that as someone who has watched some of the movies before, and not for an essay on the porn industry. I'm glad to be over that phase, but today I'm ashamed of what I've supported.
