Planet 51 (2009)

Plot:
American astronaut Captain Charles "Chuck" Baker lands on Planet 51 thinking he's the first person to step foot on it. To his surprise, he finds that this planet is inhabited by little green people who are happily living in a white picket fence world, and whose only fear is that it will be overrun by alien invaders...like Chuck!

My Comment:
"You're the alien"
"No, you're the alien"

That's kinda confusing, but it was true, we are alien in other space...

Nice cartoon, but not excellent
