Muppets From Space (1999)

Other mistake: When the agent shows the spiral for the pattern of the messages, the spiral goes through South America and America. But the agent, before, showed two messages that aren't in the pattern; one in England (Stonehenge), the other in Cairo, Egypt.

Continuity mistake: When Rizzo is with the other lab rats and David Arquette says about having a funny boy, he bangs Rizzo's little yellow cap down on his head. In the changing shots, the angle of the hat alters about 5 times; sometimes it is on straight, then its half cocked to the side and at one stage it is on completely backwards.

Continuity mistake: In the scene with the Captain Alphabet messages, we see the words "watch the sky" being formed in a clear space on the tablecloth, but when Rizzo comes to look, the tablecloth is suddenly littered with cereal, many of the letters not even used in "watch the sky". When the words "are you there" appear, the tablecloth is once again clear.

Trivia: This movie is based on a scene from the original Muppet Movie, where, while sitting around a campfire, Gonzo sings "I'm Going Back There Someday," and looks up at the night sky (though nowhere in any other Muppet show or movie does it say he's an alien).

Miss Piggy: Midnight. The lone alien stands before a naked sky. The mood is tense. My hair looks great..

Agent Barker: We feel your pain, Gonzo.
Gonzo: They feel my pain.
Rizzo: I've got a paper-cut that's a doozy. You feel my pain, too?

Ubergonzo: Gonzo, by surviving and thriving on this alien planet, you have proven yourself audacious, courageous, and distinctly one-of-a-kind. We welcome you back with our most ceremonious of ceremonies.
Gonzo: What's that?
Ubergonzo: We gonna blow you up, baby.
