The first poster is online for one of 2011's most eagerly awaited films: Paul, the next hilarious adventure from comedy giants Simon Pegg and Nick Frost. Directed by Greg Mottola (Superbad), the film boasts a phenomenal line up of jokers including Seth Rogen (voicing the alien in the title), Bill Hader and Kristen Wiig, and also stars Sigourney Weaver, Jason Bateman and Jane Lynch!

Here's our account of a truly unique visit to the set a few months back, and hit the jump for the full poster, synopsis and trailer.

Here's the official synopsis:

Simon Pegg and Nick Frost (Hot Fuzz, Shaun of the Dead) reunite for the comedy adventure Paul as two sci-fi geeks whose pilgrimage takes them to America’s UFO heartland.  While there, they accidentally meet an alien who brings them on an insane road trip that alters their universe forever.

For the past 60 years, an alien named Paul has been hanging out at a top-secret military base.  For reasons unknown, the space-traveling smart ass decides to escape the compound and hop on the first vehicle out of town—a rented RV containing Earthlings Graeme Willy (Pegg) and Clive Collings (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.
