"Doggonit, Ben! I'm not a superhero. I'm a Latter Day Saint."
Orgazmo is a low budget live action film by Matt Stone and Trey Parker. In their typical style, it spans the full range of humour, from crude sexual and toilet humour, through to jokes that betray their well known Monty Python influences, all the way to Charles Dickens quotes.
While simultaneously sending up porn, Mormonism and martial arts films (none of which are things I can claim to be very knowledgeable about), Orgazmo still adheres to the monomyth, and is arguably at least as well written as most serious films.
Due to its small budget and its sexual subject matter unfairly giving it an NC-17 rating in the US, it's not as popular as their next live action film, Baseketball. This is, in my opinion, crazy. In spite of its subject matter, it doesn't have any explicit sexual content beyond a quick glimpse of an actress's breasts or an actor's hairy bum. While you wouldn't exactly watch this film with your family, everything that happens is played for laughs, never arousal. Nevertheless, the MPAA fear the general public discovering sex, as Stone and Parker talk about in This Film Is Not Yet Rated.
All in all, aside from a few puerile fart jokes and breast related tacky sound effects (seriously, Yanks, us Brits have moved on from Benny Hill), this is generally a funny film. If you like South Park, this is clearly the same kind of humour by the same people. It's not great, but it is underrated.
