Have you seen it? I saw it the other day. I watched it at around 3 AM Saturday night. It's from 1985 and I only learned of its existence a number of days ago when Netflix told me about it and I added it to my queue.
It's a dark comedy. There's something uncanny about it. It's one of those movies where the hapless main character stumbles through an unfortunate series of events and things just gradually spin out of control. It's probably one of the best of this type.
It takes place in SoHo. Today I walked around SoHo and actually found by accident one of the locations in the movie. (I'm pretty sure.)
You should rent it. And then watch it. And then return it, so that other people can rent it.
Prepare to get very nostalgic for 80's New York.
