''Planet 51'' is a Spanish/American AllCGICartoon feature from 2009. The premise: Human astronaut Captain Charles "Chuck" Baker ([[Creator/DwayneJohnson Dwayne "the Rock" Johnson]], accompanied by an exploration robot named Rover, lands on the eponymous planet, which is supposedly uninhabited. However, Planet 51 ''is'' populated, by green-skinned humanoids whose world strongly resembles 1950s suburban America. The aliens are also paranoid about being invaded by another planet, so Chuck's appearance causes unintentional havoc, and he's soon being hunted by the military. Chuck befriends an alien teenager named Lem (Creator/JakeLong), a worker at a local observatory; Lem protects the astronaut as he struggles to return to his ship, which will automatically take off after a preset time limit whether Chuck is aboard or not.

* KnowNothingKnowItAll: Professor Kipple claims to know everything about humans but he believes they mind control powers and when he finds the wrapper for the Twix, he claims that it is a declaration of war clearly because he cannot read a single word.

* FourFingeredHands: The aliens have them. [[{{Lampshaded}} "Gimme four!"]]
** Chuck actually has five fingers.

** The aliens can function without [[spoiler:a brain]], and might even be ''smarter'' that way. Which just leads to the question of why they think it's important, but...

--> "If you have to go number one, aim for the newspaper. If you have to go number two, go outside. If you have to go number three, I can't help you."

** Another example of ArtisticLicenseAstronomy, not to mention SciFiWritersHaveNoSenseOfScale: at one point Chuck mentions the alien planet is 20 billion miles away from Earth. In RealLife, the nearest star to our solar system is 24.7 ''trillion'' miles away. Which may be FridgeBrilliance: he mentions at some point that the only thing he does with the star ship is to push some buttons, like a monkey could do. Chuck isn't exactly the brightest bulb of the set...

* ArtisticLicenseAstronomy: An InUniverse example. According to Lem's observatory lecture at the beginning of the film, "the universe is nearly 500 miles long, and it contains--you're not going to believe this--over 1000 stars!"

The first animated film by [=TriStar=] Pictures.

* RaceAgainstTheClock: Chuck's ship is programmed to leave in 74 hours--with or without him. [[spoiler:He makes it.]]

* RobotDog: Okay, so little Rover's not a literal robot dog, but his behaviour is deliberately mimicking that of a dog. Everything he does, whether tracking Chuck, interacting with alien pets, or being caught - and the other characters treat him just like a dog too.

''Planet 51'', a Spanish/American AllCGICartoon feature from 2009, is an AffectionateParody of tropes from both ScienceFiction and {{Sit Com}}s of TheFifties.

* {{Expy}}: The Aliens' pets look like [[Franchise/{{Alien}} Xenomorphs]] that are about the size of a toy poodle. Instead of a second set of jaws, they have a sucker mouth on a frog-tongue.
** They don't bleed acid, though. They ''piss'' acid.
