Actors Tina Fey, Christopher Guest, Jeffrey Tambor, and John Hodgman have joined the cast of This Side of the Truth, giving the film one of the best comedy line-ups this side of... well, a Christopher Guest movie. They join writer-director-star Ricky Gervais, Jennifer Garner, Rob Lowe, Jonah Hill, and Louis C.K. in a movie set in a world in which lying does not exist until Gervais' character invents it to get ahead in love and business. Matt Robinson co-wrote the screenplay and will share directorial credit as well.
It's a little high-concept but how can you go wrong with an ensemble this good.
