Trivia
For the pit-scene a fake alligator was used, as well as real ones. To calm the alligators down they were put in cold water. For a certain scene, Gerard Depardieu's stuntman was supposed to jump on a model-alligator and surf across the pond. Unfortunately, the stuntman made a mistake and jumped on a real alligator. He just managed to get away fast enough without being hurt by the animal.
In the movie it is established that Getafix's magic potion works only for "about ten minutes". However this is a big contrast to the original comic books where the magic potion did in fact work for many hours (if not days)
There were about 100 real spiders in this movie. The crew made them harmless by putting wax on their teeth. Each night they were counted. By the end of the movie some of them had escaped. Most died because of the cold, but one spider survived and was later found on the set. The local firefighters decided to keep the spider as a mascot.
