What's the worst-case-scenario for a honeymoon? If you answered ‘one of the newlyweds is abducted and turned into an alien host,’ then you must have already seen Honeymoon. Honeymoon is the only movie on this list with a female director, Leigh Janiak. It also stars Rose Leslie, known for her role as Ygritte on Game of Thrones.

For their honeymoon, Bea (Leslie) and Paul (Harry Treadaway) decide to stay in a cabin in a remote forest (which, if they'd seen any of the other movies on this list, they'd have known was a bad idea). The locals tell Bea and Paul to leave, but the two think nothing of the warning until Bea disappears one night, and is later found naked by Paul in the woods. But now that Bea's back, she's ... different. The honeymoon period is over, and so is Bea and Paul's chance at marital bliss.
