Timeshift reveals the ten commandments of big cinema as it goes behind the scenes of the biggest film genre of them all - the epic. See the biggest sets ever known! Hear the sound of Ancient Rome! Count the spiralling costs as budgets soared!

Today, the epic lives on in the Oscar-laden Gladiator and the spectacular sweep of Avatar. As this documentary reveals, the stories behind the films are as spectacular as the films themselves. Show less
