The first trailer for the comedy The Invention of Lying has hit the web today, via UK Yahoo.

Once known as This Side of the Truth, the concept of the film is: ‘Imagine a world where everyone can only tell the truth. And no-one has ever lied.’

From there it’s comedy gold!

Joining Gervais in the film is a top shelf cast: Jonah Hill, Louis C.K., John Hodgman, Tina Fey, Christopher Guest, Jeffrey Tambor, and Jason Bateman.

The Invention of Lying arrives in theaters on September 25th, 2009.
