An American Werewolf in London (1981)
Director: John Landis

Definitely a big inspiration on Shaun in terms of the tone. It combined so many things: big belly laughs, sympathetic characters, full-on gore, amazing special effects, and one of the first ironic pop culture jukebox soundtracks. The combination of werewolves and blood and naked females was burned into my synapses as a 9-year-old kid. It's so deadpan and brilliant. There's a bit in Shaun that we take straight from American Werewolf: closing the bathroom mirrored cabinet and seeing somebody behind you. It's one of those films I could endlessly watch.
