An American Werewolf in London is a 1981 American-British horror comedy film written and directed by John Landis and starring David Naughton, Jenny Agutter and Griffin Dunne. Two young American college students, David Kessler (Naughton) and Jack Goodman (Dunne), are attacked by a werewolf on a backpacking tour of Britain and are attacked by a werewolf. One is killed, the other is mauled. 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, telling him he has now become a Werewolf and demanding that he commit suicide to release them from their curse.
