“Page Six” says the Motion Picture Assn. of America’s rating s board “just might flip out” when they see Quentin Tarantino and Robert Rodriguez‘s Grindhouse (Weinstein Co., 4.6), a wink-wink exploitation movie in quotes that’s being sold as a tribute to the cheeseball sex-and-violence flicks that used to play in urban downmarket movie theatres in the ’50s, ’60s and ’70s.

Wait a minute…”might” flip out? As in “they haven’t seen it yet”? A little more than two weeks before opening? I don’t think I believe that. The Weinsteiners are looking for an R rating but “some of [the film] is so graphic and outrageous for a major Hollywood studio, there’s no question it’s headed for an NC-17 without big cuts,” says a ‘Page Six’ operative who got a sneak peek at the most over-the-top footage.”

So the risque footage may show up on the DVD instead of in theatres? I think most of us understand that system and are actually quite accustomed to it.
