Query: Cripple + Girl + Killer hitch-hiker = A good movie!

The movie goes as follows: A woman (Lara), sick of her husband, runs away to her friend's place to stay. Along the way, she picks up a seemingly innocent hitch-hiker (Justin McKay) who bites his fingernails and wears a polaroid camera around his neck. He's going to see his psychiatrist. On their way to "Hendersonville," a series of grisily, but rather cute, murders are committed by Justin. This is a pretty good movie, but I don't think it would be all that great if it didn't have Mark Hamill in it. He plays a good nut (no offence). The movie storyline leaves something to be desired. But, overall, the action, the acting, and the ending keep you on your toes.
