It's Springgggggggggg! Let's celebrate with a Mario Bava film about the joys of the coming season and also, you know, demonic possession.
This movie is a gas. It not only has perhaps one of the most brilliantly executed jump scares in horror history, it also has that fucking kid. I used to have a roommate named Mark and I sampled that intro line into our answering machine message -- “this is Jay, Brent and Marco, that's my name! Leave a message” -- much to his utter confusion. Ahh, good times.
