The UK trailer for Greg Mottola's Paul has landed online.  Starring Simon Pegg and Nick Frost, Paul tells the story of two geeks who come across an alien named Paul (hence, the title) while road-tripping across the US.  Everything I've seen of the film thus far has led me to believe it is going to be a great time and this latest trailer only builds on that expectation.  After watching it, the only question I might ask is, "does the film have any more 'ball jokes' up its sleeve?"  Let's hope so.

Hit the jump to check out the trailer for yourself.  In addition to Pegg and Frost, Paul features an all-star cast that includes Jason Bateman, Kristen Wiig, Sigourney Weaver, Jane Lynch, Bill Hader, and the vocal talents of Seth Rogen (as Paul).  The film is slated to open in the UK on February 18, 2011 and stateside a month later on March 18th.

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 (voiced by Seth Rogen) 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.
