I've read this movie pokes so much fun, at darn near -everything- and -everyone-, that some in hollywood, who are parodied in this film, are already talking of suing the producers.
It looks to me, to be "much fun", though perhaps not for general family consumption. I'll probably have to wait till it comes out on video, but I -am- looking forward to a great laugh.
Lettuce know how it turns out.
