I was actually in this film (I played one of the Almighty Swans) and am extremely surprised AND upset that my name was not mentioned in the credits. I spent over a month and a half working on this film. To not be mentioned in the credits is absolutely discourteous and unethical. Give credit where credit is due.
As far as the movie goes, it's "typical National Lampoons humor". If you like it, you'll most likely enjoy the film. If it's not your bag, then I wouldn't bother. The film is a bit discontinuous and lacks in depth. If nothing else, watch it for the FABULOUS Almighty Swans that didn't make the credits. I'm sure that most of the Fearsome Foxes didn't make the list either...
