David and Jack are studying at an American university, but they will one day be exposed to an exciting and frightening incident. The disaster begins when they are attacked by a huge wolf, with both students carrying their bags through Britain. David managed to escape from that savage attack a large figure in the body, but Jack would kill the wolf. David remained in the hospital wounded until he recovered from the bite but suffered from nightmares from his deformed friend, who still comes to him in his sleep every day and warns him that he has become a victim and must commit suicide. When David discovers that dreadful truth, he begins to think of suicide before the moon is complete or else will endanger everyone's life because he has become a wild wolf.
It's a failure, less because the odd stylistic mix doesn't take (it does from time to time, and to striking effect) than because Landis hasn't bothered to put his story into any kind of satisfying shape.
John Landis teaches us two things in An American Werewolf in London (1981): turning into a werewolf is a very painful process, and the dead are boring!
A clever mixture of comedy and horror which succeeds in being both funny and scary, An American Werewolf in London possesses an overriding eagerness to please that prevents it from becoming off-putting.
Seems curiously unfinished, as if director John Landis spent all his energy on spectacular set pieces and then didn't want to bother with things like transitions, character development, or an ending.
Not just gory but actually frightening, not just funny but clever, 'American Werewolf...' has its flaws, but these are outweighed by the film's many, mighty strengths.
