I remember I watched a movie years ago. It was about a guy who buys a spider monkey for his kid, and throughout the movie the monkey starts killing. The monkey killed their dog, and then it began to terrorize the family. One scene I remember is him and his wife are sleeping on a pillow couch in the living room, the husband heard a noise, rolled over and the monkey had stabbed his wife in the neck. What movie is this?!
Teror Tract. Starring Bryan Cranston!
