Star Wars creator George Lucas makes a cameo appearance in the sci-fi series' final instalment Episode III - Revenge of the Sith - but only eagle- eyed fans will spot him.

The 61-year-old originally only intended to include his daughters in a busy crowd scene, but they insisted he join them in full galactic gear.

Lucas is recognisable because of his trademark bushy beard. He says, "There is a scene, a large crowd scene, which my daughters are in and they sort of insisted that I be in it, and so I did it."
