Seth Rogen, Jason Bateman, Bill Hader and Jane Lynch have joined the cast of Paul, the new comedy from Superbad director Greg Mottola, that will star Shaun of the Dead and Hot Fuzz duo, Simon Pegg and Nick Frost. The film was penned by Pegg and Frost, and centres on the geeky twosome as they venture on a cross country trip through America, so they can get to nerd mecca, Comic Con. Along the way they meet an alien called Paul, who will be voiced by Rogen. It's a fantastic supporting cast and director, so this could work very well for all concerned. Mottola last directed the very well received Adventureland, which is released in September.
