There is one good thing about watching The Adventures of Baron Munchausen... you at least get to see a young Uma Thurman. It's always fun to watch one of your favorite actors before they were huge. It's especially good to see Uma Thurman pre-Kill Bill since she suffered from a horrible injury on a stunt-gone-wrong during the filming of the movie. That's one of the pieces of Kill Bill history audiences like to forget so that we don't get sad while watching Uma Thurman cut men in half.
A VHS of The Adventures of Baron Munchausen can get you a pretty penny if you are still holding onto one after all these years. If you don't have one, you might want to check your local landfill. You might be able to find a copy there.
