Help me please!!!

I just happened to stumble on this movie title and I think it might be a movie that remeber from years ago that I thought might have just been a dream. I need to confirm that this was that movie, so I need to ask a couple questions.

Is there a scene in a dungeon where they show a silhouette of a man trapped inside a gigantic drum?

Do the kids where novelty hats with a pair of clapping hands on top of them?

Does Dr. T have something against people who play wind instruments like flutes?

Thanks alot.
