There's a movie I saw back when I was little. I don't remember the plot too well, but it's a comedy.

It's set in a haunted hotel. I think someone was trying to make a profit from the hotel, although they knew it was haunted. I remember some scenes from the movie: the chef of the hotel is making food, and he's about to chop of the head of a fish. After he's chopped off the head of the fish, the fish head starts/resumes whistling. I also remember that they were watching a play about the sea where they had these moving backgrounds and stuff. There was a cracken in the set, which came alive, and dragged a little boy into the set, making him a part of the moving background.
