Tina Fey by Shawn Ehlers/WireImage.com
Ricky Gervais is assembling a diverse, star-studded cast for his upcoming film, This Side of the Truth - and he just added four more talents to his roster, starting with Tina Fey.

Along with the 30 Rock star, Gervais has also tapped Christopher Guest, Jeffrey Tambor and Daily Show correspondent John Hodgman (aka the PC man to Justin Long's Mac) for the flick. They'll be joining a cast that already includes Jennifer Garner and Jonah Hill, among others. The film imagines a world in which lying doesn't exist (seriously). When a dorky "loser" (played by Gervais) invents the concept, his own world, not surprisingly, changes exponentially.

What's your take on the lineup? Are you ready for a Gervais-led film? Or wish he would stick to the small screen? - Anna Dimond
