This played Sundance I think last year. It's crazy. It's like a not-at-all creepy David Lynch. It's very hard to explain. But you have a writer of an autobiographical book, and the book is being adapted into a movie. The film follows the author, the actor playing the author, the filmmaker making the movie, and also the author of the REAL book/actual director of the movie, JJ Lask.
If you think Charlie Kaufman is meta, then you haven't even scratched the surface of On The Road With Judas. There are some of my favorite actors in the film too - Kevin Corrigan, Aaron Ruell (from Napoleon Dynamite), and that guy from American Pie Eddie Kaye Thomas is in it too. It's a real mindfuck of a movie - it's kind of like the movie version of a really hard sudoku problem, but really rewarding when it all comes together.
And unlike a lot of other films that are about themselves - it never sacrifices human emotion for the sake of it's cleverness. At it's very core is an honest love story, that is very well drawn.
