Gremlins (1984)

Billy Peltzer receives a mysterious creature called a mogwai as a Christmas gift, along with three strict rules: keep it out of light, don’t get it wet, and never feed it after midnight. When the rules are broken, chaos erupts as mischievous, monstrous gremlins terrorize the town. Blending horror and comedy, Gremlins is a darkly humorous holiday story about unintended consequences and responsibility.
