The New York Underground Film Festival hasn’t released their lineup yet, but some of the films playing will be Each Time I Kill and Blood of the Earthworm.
The SouthSide Film Festival isn’t an underground film festival, but they are showing some underground films by Don Hertzfeldt, David Chai and Henry Selick.
Rejected by Don Hertzfeldt is a short underground animated film that was nominated for an Academy Award. It didn’t win, but it should have. It’s amazing.
