Poultrygeist: Night of the Chicken Dead. Yes its a real movie.

It has a website and everything. Its playing in one theater in Manhattan. There is a NSFW trailer on the website that makes this movie appear to be the nastiest, goriest most absurd film of all time that you can't believe anyone actually got made.

"I know, lets have the half chicken/half human zombie reach through the grave and into this dude's ass and then through his body."
"Great idea"

If you want to watch the NSFW trailer its on the website. I don't recommend it.
