In Hollywood, the story beats of werewolf movies were codified in 1941 by a German-Jewish emigrant to Hollywood via London named Curt Siodmak, who wrote the seminal film 'The Wolf Man', starring Lon Chaney, Jr.

40 years later, John Landis made the most important and enduring and influential werewolf film ever made in 'An American Werewolf in London'. It was his follow-up to the one-two punch of 'Animal House' and 'The Blues Brothers'.  He could make any film he wanted, with anyone he wanted. So he made a script he'd begun when he was 18 years old. A script he'd first discussed with an aspiring special effects and creature-design guy named Rick Baker in 1971.  10 years later, he'd found two unknown leads, hired basically the entire cast of an acclaimed touring production of 'Nicholas Nickleby', and called Baker on the set of another werewolf movie ('The Howling') and convinced him to decamp to England to work on 'An American Werewolf in London'.  For his groundbreaking innovations on the film, Baker won the ver first Academy Award ever given for makeup special effects.

Featuring a snappy, smart script, Landis' virtuosic comedy/horror chops, and an unexpected soundtrack of moon songs, 'An American Werewolf in London' is in a class by itself and is one of the most important films ever made.

"Werewolf of London' inspired Zevon's song 'Werewolves of London'. Phil Everly of the Everly Brothers had watched the film and told Zevon jokingly that he should write a song with that title and start a dance craze.

And as far as listicles go, this one is well-reasoned by someone who knows their werewolf films:
