Trivia / The Invention of Lying

• Deleted Scene: The DVD shows us the original opening with the cast as cave people (including a cameo by Karl Pilkington). Cave!Mark tells the first lie, saying he slew a giant predator, which makes him popular with the ladies and he passes the ability to lie on to future generations. Then we see the world as it becomes if he doesn't lie, leading to the present as it appears in the film.
