9. David Kessler - An American Werewolf In London
An American Werewolf in London sees two American backpackers, David (David Naughton) and Jack (Griffin Dunne), attacked by a werewolf while out on the Yorkshire moors.
Jack is killed but David survives, albeit while having unknowingly become a werewolf himself. Though an increasingly grisly vision of Jack urges David to kill himself before the next full moon to avoid turning into a werewolf, David refuses to believe him.
This comes to a brutal head when, on the next full moon, David indeed turns into a werewolf and kills six people across London, before waking up naked in London Zoo with no memory of what happened the night before.
It admittedly doesn't take David long to piece things together, but as he wrestles with what to do about his situation, he again transforms and commits another savage rampage.
Though a fleck of David's humanity is briefly perceptible during the climax - he fleetingly recognises his lover, Alex (Jenny Agutter) - he's ultimately shot and killed by the police before reverting back to naked human form, albeit dead.
