Saw this at the theater when it first came out. It was okay. But years later at a sci-fi/fantasy convention, they were playing this in the theater at the hotel the convention was being held.
When the scene of Ming's chief henchman (can't remember his name) called for the bore worms and the princess cried out, "No, not the bore worms!", I stood up and shouted, "Yes! Yes! The bore worms!" Then immediately sat down as if nothing happened.
Everyone in the place was looking around for the outburst. My friend with me just gave me a grim sidelong glance.
