Latino Review pointed out that the Paul poster is copying The Social Network poster by using one-word descriptions.  What do you think?  I think an alien is an alien. Seth Rogen is the voice for Paul, the alien.

Paul has been hanging out at a top-secret military base for more than 60 years and it finally dawns on him to escape the compound. He hitches a ride on the first vehicle, which is an RV driven by Graeme Willy (Simon Pegg) and Clive Collings (Nick Frost).

Chased by federal agents and the fanatical father of a young woman that they accidentally kidnap, Graeme and Clive hatch a fumbling escape plan to return Paul to his mother ship. And as two nerds struggle to help, one little green man might just take his fellow outcasts from misfits to intergalactic heroes.

Other cast members include Kristen Wiig, Sigourney Weaver, Jeffrey Tambor, Bill Hader, Jason Bateman, Joe Lo Truglio and Jane Lynch.

The science fiction comedy opens March 18, 2010.
