Planet 51 (2009)

This is an okay movie. Astronaut Chuck Baker (Dwayne Johnson) expects to be the first human to land on a distant planet, but is startled to realize that an alien civilization already resides there. The planet seems to come right out of the 1950s and Chuck is instantly declared an invader. Previously, a robot named "Rover" had been sent to explore the land, but with its myopic mission of only seeking out rocks, failed to report the life. The local military wants to take the spaceman into custody, but a teenage alien named Lem (Justin Long) tries to protect him.

I liked the animation and especially the rover, but the story and dialogue weren’t very good. One of the characters working in a planetarium claims the universe is only 500 miles across. The diameter of our moon is over 2,000 miles. This is the most expensive film ever produced in Spain. The name Lem refers to the Lunar Excursion Module. Chuck mentions that he needs to be back to attend the Nickelodeon Kid's Choice Awards, and this year Dwayne Johnson was the host of the show.
