If you’re bummed about an 85-degree Halloween forecast, this horror chiller can double as some winter wish fulfillment. Set in a remote Antarctic camp, a group of scientists are beset by a shapeshifting alien that causes violent tendencies in its chosen host. As the thing hops from body to body, friends are turned against each other, forced to guess who is really themselves and who isn’t before it’s too late. One of the best horror scores ever by spaghetti Western maestro Ennio Morricone adds to the suffocating atmosphere of icy paranoia. – Lina Fisher
