The first rule of “The Monkey” is there are no steadfast rules to “The Monkey.” This is a blood-red dark comedy about a toy monkey who is evil incarnate and has the supernatural ability to kill people in a variety of creative and gruesome ways, and either you go with that or you don’t.

Theo James has dual roles as twin brothers whose lives have been hell since finding a cursed monkey when they were kids in "The Monkey."
