Like Roger Ebert, I have to give some credit to a film that does what it sets out to do and has no illusions about social value or artistry. That's "Hanger" in a nutshell. Pure exploitation from start to finish. (This review refers to the uncut edition, as though a cut edition would be any better.)
Perhaps one of the most striking things about the film (other than an obsession with genitalia) is the heavy use of facial appliances. There may be two male actors who are not heavily covered with facial appliances throughout the film (and I have my doubts about one of them). Female roles fare a little better, trading "money shots" for not having to wear prosthetics. The whole thing comes off like a medieval allegorical play, with all the players in masks representing their roles.
Overall, not as funny or interesting as "Gutterballs." It is much more extreme than "Run, Bitch, Run," which hardly rose to the level of exploitation anyway. And it's not nearly as creepy as "deadgirl," which is in a completely different class of film-making (i.e., much superior).
The best use I know of for "Hanger" is to show somebody an exploitation film that exists for no other reason than to exploit. Still, you gotta admire honesty.
Not recommended for people with reasonable standards of decency or any expectations of artistry.
