 In some versions of the film shown on TV in the UK, a scene was cut between  the main characters return from the animated island and the first use of the  substitutiary locomotion spell, which shows the medallion they stole from the  King disappearing, and then them realizing they could still get the complete  spell from the young boys comic book, in which a picture of the medallion is  printed. This cut makes it appear as though they still have the medallion,  and were able to get the complete spell from it.
