An American Werewolf in Paris is not a sequel to the classic An American Werewolf in London movie. Although they may fall in the same An American Werewolf Series but this rather 'modern' werewolf was not well accepted by fans in general. In this movie werewolves had the choice of turning into one at any point of time with help from a serum - so there goes the trademark for werewolf movies - the moon - the full moon.
Unlike in An American Werewolf in London, the Paris counterpart did not have that umph in it - the scene where werewolf lovers get their kick from - the transformation scene. I think this is because a different technology was used in making the transformation in this movie compared to the real hard work the guys had to go through in An American Werewolf in London. I do feel that computerised horror flicks or CGI created horror characters, whatever you may call it are just unrealistic and it limits the creativity of the film maker, unlike when they had to physically put make up on actors to make them look scary.
Having said all that I still enjoyed the movie (and yes, I've watched it a million times!)
The following is from Wikipedia:
An American Werewolf in Paris is a1997 horror/comedy about werewolves . It was directed by Anthony Waller and starred Tom Everett Scott and Julie Delpy. It follows the general concept of the1981 film An American Werewolf in London .
The title of this film has a bit of history; when production of the original London film ran into trouble with British Equity, director John Landis, having scouted locations in Paris, considered moving the production to France and changing the title of his film to An American Werewolf in Paris.
In the opening scene, a man is seen under attack, almost managing an escape from the Parisian sewers before an unseen creature pulls him back. Meanwhile, tourist Andy McDermott is seeing the sights of Paris with his friends Brad and Chris. When Serafine Pigot 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 seen 16 years ago in the earlier film.
Andy tracks her down and asks her for a date. They attend a night club called "Club de la Lune" (literally translating to "Club of the Moon"). It was called like that, because that night was a full moon in the sky. The owners of the club were actually members of a werewolves's society, which wanted to kill and eat all the guests. Serafine told Andy to run away (in that scene, Serafine is seen transforming into a werewolf). When Andy is running it is seen a werewolf chasing him and when Andy is about to escape, it bites him and Andy faints. The next day, he wakes up in Serafine's 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 raw steaks. Serafine explains that her stepfather (seen in the film's opening scene) has been working on a drug to control her werewolf transformations. The real cure lay in killing and eating the heart of the werewolf that bit him.An American Werewolf in Paris was poorly received by most critics. The review aggregation site Rotten Tomatoes lists the film as "rotten", with only 10% of reviews positive based on nation and worldwide ratings. Unlike An American Werewolf in London, which had Oscar-winning special make-up effects by Rick Baker, Paris relied heavily on CGI for its transformation effects and chase sequences, a common point of derision from most critics. According to box-office sales and online reviews, this sequel proved to be much less successful than the first film.
