Paul, a new comedy starring and written by Shaun Of The Dead, Spaced, and Hot Fuzz co-stars Simon Pegg and Nick Frost has announced some casting choices. Variety, which inimitably describes the film as a "road trip laffer," has revealed that the cast will include Jason Bateman, Jane Lynch, Kristen Wiig, Bill Hader, and Seth Rogen, the lattermost providing the voice an alien. This is the first Pegg / Frost pairing on which Frost has a writing credit, the previous films having been co-written by Pegg and director Edgar Wright. It's also the first such team-up with another director. Greg Mottola of Adventureland and Superbad fame will be taking the helm.

As for the plot:

Pegg and Frost, who wrote the script, will play two science-fiction fanatics on a road trip whose conspiracy dreams come true when they trek to Area 51 and encounter the title character, an escaped alien.

Color us intrigued.
