Richard Elfman’s “Aliens Clowns & Geeks” is the type of indie zaniness you’ll only find in back room of modern cinema. It’s a fearless, and bizarre mish mash of comedy, satire, science fiction, music, and just about everything else you can find. There are transgender individuals, and evil clowns, and a hero who can fire lasers out of his anus. And that’s really the tip of the iceberg when you manage to soak it all in. And you’ll need a hell of a lot of booze and weed to soak it all in.
