Planet 51 (2009)

Continuity mistake: As Chuck first arrives on Planet 51 he takes a few steps. The ground in front of him is clear. As he plants his flag down he steps on a duck which wasn't there before.

Low Cow

Lem: Lem. Llllleeeeeemmmmmm.
Charles Baker: Either your name is Lem, or you want to mate with me. Houston, we have a little problem.

Trivia: When the Hazmat team are dropping objects into the containment pod, they drop in a magazine called "G.A." On the cover are a number of titles regarding the making of the movie, including one that reads, "G.A.'s Lifestyle Advice: Go to the Movies to see Planet 51."
