This British-Dutch-Luxembourgian co-production is based on characters created by John Landis for his An American Werewolf in London (1981). In the opening, a man is seen under attack, almost managing an escape from the Parisian sewers before an unseen creature pulls him back.
Meanwhile, tourist Andy (Tom Everett Scott) is seeing the sights of Paris with his pals Brad (Vince Vieluf) and Chris (Phil Buckman). When Serafine (Julie Delpy) leaps off the Eiffel Tower just before Andy is about to do a bungee-jump, he executes a mid-air rescue.
She vanishes into the night, leaving Andy intrigued -- and also unaware that she is the offspring of the couple (Jenny Agutter, David Naughton) seen 16 years earlier in An American Werewolf in London. Andy tracks her down, asks for a date, attends a party, and winds up in her bed.
When he awakens, he has toothmarks on his leg and is informed that he's making a transformation into a werewolf, confirmed by his sudden taste for rare steaks. Serafine explains that her stepfather (seen in the film's opening scene) had been working on a drug to control her werewolf transformations.
Beneath a full moon, the lycanthropic love story continues. Filmed in Luxembourg, Amsterdam, Paris, and New York, with special effects mainly from California's Santa Barbara Studios. Werewolves were created by combining prosthetic devices and animatronics with computer-generated creatures.
