How might a kid — OK, a teenager — protect himself from that dreaded fate described in legions of sci-fi movies (including The Fourth Kind), the anal probe? If you aren't thinking "champagne cork," you are way, off according to the sci-fi kids cartoon Planet 51.
A genial but generic riff on sci-fi movie history, Planet 51 has barely enough slapstick to keep the kids interested. Children won't get the many sci-fi movie references — or the cork gag — and adults probably won't find them that funny.
But there's an adorable Mars Rover-like robot named "Rover" who wags his antenna and chases rocks like a Jack Russell terrier, and an alien Chihuahua shaped like the beast from Alien. He scooches his butt across lawns and carpets just like a real Chihuahua. But don't ask what happens when he pees.
The big joke here — given away in the movie's trailers — is that an alien has "invaded" a provincial and paranoid suburban town on another planet. And the alien is us, a NASA astronaut who touches down, bounces out with his American flag (humming Thus Spake Zarathustra from 2001), only to realize he's interrupting a barbecue. Astronaut Chuck Taylor (voiced by Dwayne Johnson) has discovered an alternate 1950s — with drive-ins, doo-wop music, "duck and cover" drills and VW hover-Beetles.

His first thought: "Kennedy's gonna freak" when Mission Control hears about "sea monkeys dancin' to the oldies." But the "sea monkeys," conditioned by years of It Came From Outer Space horror movies, are the ones who freak.
Lem (Justin Long) is the odd, antennae'd E.T. that Chuck talks into helping him get back home, evade the trigger-happy Army general (Gary Oldman) and the jumpy natives who are sure that the guy in the puffy suit wants to eat their brains.
This first offering from Spanish animation start-up Ilion is a good- looking movie, with a lush retro- futuristic design. It's just low on laughs (an American Shrek alumnus scripted it).
The superior Monsters vs. Aliens covered some of the same ground — references of earlier movies, from Alien and E.T. to 2001, The Right Stuff and, naturally, Plan Nine From Outer Space. Some of those work.
But spoofs, a couple of cute neo-dogs and lots of bouncy '50s pop on the soundtrack don't hide the fact that, whatever the magical code is to concocting a state-of-the-art kids' computer-generated cartoon these days, Ilion (working for Sony-Tristar) hasn't cracked it.
