Hayden went to Australia for a month to train specially with the lightsabre.
He said: "It was just every kid's dream. I can't wait to go back and train for Episode 3."
The lightsabre gave Hayden a "good workout" because it's so heavy and he had to learn how to swing it just right.
All in all he reckoned it was "absolutely thrilling!"
Star Wars Episode II: Attack of the Clones opens in the UK on 16 May.
