"Planet 51" - a new take on the alien invasion film

Planet 51 is a CGI film. On the titular planet is a race of aliens with a lifestyle that is as similar to ours as it is different (they have four fingers, but they speak English, for instance). One of the inhabitants, Lem (Justin Long), works at the local planetarium part-time, but plans to work full-time upon graduation. Lem believes that the universe is smaller than it really is. One day, an astronaut from Earth named Charles "Chuck" T. Baker (Dwayne "The Rock" Johnson) lands on Planet 51, unaware of the life on it. To the "aliens" there, Charles is now considered an "alien" and some of the inhabitants are after him. Chuck enlists the help of Lem to escape captivity and to prove his innocence. In a subplot, Lem has fallen for his neighbor Neera (Jessica Biel), but a hippie alien named Glar (Alan Marriott) also loves her. Neera starts to question Lem's views on alien life as he says something that makes him seem like he's against it. Another subplot involves one alien growing attached to Chuck's probe, Rover (also Justin Long).

I know this has been done before, but never like this. I mean, if the other films are how humans react to aliens on their planet, how do you think aliens would react to humans? Now, granted, this has been done earlier this year with Battle for Terra, but that was a sci-fi action flick. This is more of a comedy. Also, he seems to just be exploring, not trying to take over the planet (though he is accused of the latter). I also liked some of the pop-culture references and jokes (see the MPAA section) that may go over kids' heads, Glar's "Stick it to the Man" song was pretty funny (heck, Glar himself made most of the film), and "The Rock" is near unrecognizable.

The film scored a PG rating. The aliens chase Chuck with weapons trying to subdue him, and some other slapstick material is present. In one scene, an army of aliens talk about who will shoot who in case of betrayal. Chuck pretends to zombify some aliens (sometimes as playing, sometimes to scare away a crowd). There is some minor sexual stuff... for instance, a probe named Rover (also Justin Long) "urinates" oil, and an alien "dog" has acidic urine. An alien wears a V-neck top that reveals cleavage, and another alien looks there when the female alien says "Look at the sky", and Chuck is seen in nothing but a towel as aliens try to dissect him. He gets up and takes his towel off (we don't see anything, but an alien does) and one of the aliens says, "That's a funny place for his antenna!" After Chuck lands, he steps on a rubber ducky and says, "What the... duck?"

Well, if you're interested in a comedy film that uses alien clichés in reverse, or just something that tells the truth about paranoia, then this is your film! And stay tuned a little into the credits for another scene.
