The cards Annie Wilson uses to perform her "readings" are actually Zener Cards, which are used to perform ESP tests. The cards are not known for their fortune-telling abilities, but this is not necessarily a mistake. Fortune tellers can use a variety of cards from tarot decks to ordinary poker cards to give readings. All that truly matters is that the four elements of nature (fire, water, earth, and air) are represented in some form. Annie would still be able to deliver readings with them as long as she knew which symbols represented which element.
After Sam Raimi was hired as the director of Spider-Man (2002), the schedule for post-production of this film conflicted with his prospective work on the other movie. In the end, the two studios agreed to give Raimi more time to complete post-production on this film, so he could work on both films simultaneously.
The first UK radio spot incorrectly states the film is rated certificate 15. It was rated 18 when released theatrically, which is evidenced by the other two radio spots, and all three UK television spots. These are available on the 2001 UK DVD release.
