The Night of the Undead

Both movies are light-hearted, silly comedies about a group of friends/family who must come to terms with a supernatural being living in their midst.

"Save the Green Plant" and "The Night of the Undead" are movies with similar plot about aliens who disguises as humans and the people are trying to kill them. It's funny, weird, crazy, dark, full of twists. Such a wild ride, don't think too much and just enjoy (or prepare to be uncomfortable) while watching it.
