REPO MEN is an adaptation of the book "The Reposession Mambo".
Supposedly this new movie and Repo! were filmed around the same time, so they could both be inspired by the same material. I'll see Repo Men when it hits DVD.
Repo! was amazing. There are very few films in the same category. No movie since Rocky Horror even comes close to it. Moulin Rouge might have been as good if they hadn't cribbed all the music and dialogue from elsewhere. And if Baz Luhrmann hadn't edited it.
