I really need to know the name of this movie. I will try to describe it. It is about a kid named jack who travels to an island through a book. The film is from the 90s. There is a giant stone monster in a the film and a mermaid called Millie. There are pirates and the pirate-leader turns to gold when in a cave at the end of the film. If someone has any idea what the name of this film, tell me!
