Animated sci-fi tale set on Planet 51, whose inhabitants live in fear of an alien invasion. Their paranoia is realized when astronaut Capt. Charles "Chuck" Baker arrives from Earth. Befriended by a young resident, the astronaut has to avoid capture in order to recover his spaceship and return home.

"Planet 51 is the most ambitious project of the Spanish films. It’s about a quiet planet that is visited by a human alien. He thinks that there is no live in that planet and he only wants to be famous for having been there the first, but later he realizes that is not true. The script was written by the same author of Shrek, some famous people put their voices in this film, which has cost around 60 million dollars."

"This is an ambitious film (seven years of work) in order to be at the same level of other American super productions. Planet 51 is supposed to be in the cinemas for Christmas of 2009."
