Written and directed by Ricky Gervais and Matthew Robinson, 'The Invention of Lying' is set in a world where people can only tell the truth - if you can imagine such a place. It's all going well, though - that is until a writer, played by Gervais, not only invents the untruth but learns very quickly how lying through his teeth can be used to his own advantage. The impressive cast includes Jason Bateman, Christopher Guest ('Spinal Tap', 'Best in Show'), Rob Lowe and Sarah Palin impersonator, Tina Fey. 'The Invention of Lying' is at cinemas nationwide.
