Dead & Breakfast (2004, Matthew Leutwyler)
Dead & Breakfast is a highly entertaining zombie(ish) flick about a group of people who get lost on the way to a wedding. They stop for the night in a little town and stay at a somewhat creepy b&b. One of the guys discovers a box and opens it, unleashing a demonic power into the town that possesses all of the townspeople.
Dead & Breakfast has it all - blood, guts, dancing zombies, David Carradine, and a possessed folk band! It's pretty silly, but well worth a watch if you're in the mood for something campy.
