I just LOVE cheesy horror movies that don't take themselves too seriously .... and brother does this one know it's CHEESY!
"A hostile alien wreaks havoc on the cast and crew of an adult movie." .... basically by killing Ron and then possessing his "talent!"
2:31 seconds of NSFW funniness!
And if you doubt this is an actual movie, from IMDB: http://www.imdb.com/title/tt0988043/
See the humorous trailer (NSFW) here : http://www.yesbutnobutyes.com/archives/2009/04/one-eyed_monste.html
