Haven't seen this yet, but the plot has me intrigued. It sounds vaguely similar to Sheen's other movie, Badlands. I've always enjoyed movies about unlikely/odd couples for some reason lol.

It really pretty different from Badlands but there are some similarities... it is based on the book "Welcome to Xanadu". I read it a long time ago but remember really liking. I just checked and there seems to be a few uploads of the full movie on youtube!
