Simon Pegg and Nick Frost helmed 'Paul' Trailer

They've taken on the horror genre with Shaun of the Dead and buddy/action flicks with Hot Fuzz. Now, Simon Pegg and Nick Frost have sets their sights on the sci-fi genre with Paul, featuring the [erratic] comical wit of Seth Rogen as the titular alien and Jason Bateman as a "man in black" among others (Jeffrey Tambor, Jane Lynch, Kristen Wiig).

Reuniting once more, Pegg and Frost play two sci-fi/comic nerds on their way to Area 51 where they hope their adventure will turn up some evidence of alien life. Unfortunately for them, it does and it's name is Paul. Like a hyperactive E.T., Paul is a crude, smart-mouth lifeform whose escaped from custody and hitched a ride with the duo in an attempt to get back home. As the trailer boasts, it's the most fun you'll have seeing an alien scratch his balls (okay, so maybe I'm paraphrasing).
