An American Werewolf in London (1981) John Landis

Two American college students are on a walking tour of Britain and are attacked by a werewolf. One is killed, the other is mauled. The werewolf is killed but reverts to its human form, and the local townspeople are unwilling to acknowledge its existence. The surviving student begins to have nightmares of hunting on four feet at first but then finds that his friend and other recent victims appear to him, demanding that he commit suicide to release them from their curse, being trapped between worlds because of their unnatural deaths.

One of the best werewolf movies ever made, full of dark humor and gory thrills. As most people know, this has one of the best human/werewolf transformation scenes in cinematic history! The only other movie to show such detail is The Howling. This movie is really fun to watch, and if you are seeing it for the first time you will be shocked at some of the things you see. Great performances from the cast, and an excellent script make this a memorable experience.
