The 16-year-old English actor is currently filming DECEMBER BOYS on Kangaroo Island, Australia, and is shocked when people believe he is the 24-year-old LORD OF THE RINGS star.
Radcliffe explains, "So often people shout out, 'Hey, FRODO!' as they think I'm Elijah - who frankly is a very good-looking guy so I take it as a compliment.
"I admit when a couple of people have put have put autograph books under my nose I've signed them, 'Much love, Elijah Wood.'
"It would be a bit deflating for me if I told them the truth and they said, 'Don't bother signing it then.'"
