Rupert Grint, who plays Ron Weasley in the Harry Potter films, is so famous that he wears a duck mask to avoid identification in public.
Grint, 23, who stars in the final film in the series, Harry Potter and the Deathly Hallows: Part Two, said he wore the mask when attending music festivals to avoid the attention of fans.
The 23-year-old actor, whose character Ron is one of the key trio formed by himself, Harry Potter and Hermione Granger, has, like them, grown up as part of the global success of the stories.
He said: “I've never been anywhere in the world where people haven't known who I am and because I'm ginger I stick out like a beacon.'
After he was identified in the crowd at the 'V' festival he was lifted and carried by the crowd.
The actor, who is estimated to have made up to £28million from the films, explained: “It's difficult at festivals because there are masses of drunk people around, so for a couple of years I've worn an animal mask.
“The year before last it was a duck and it completely worked.”
He has faced unusual requests for autographs and has had body parts thrust at him for his approval.
Last month, he at The Wizarding World of Harry Potter in the Universal theme park in Florida when a middle-aged woman proffered a tattooed buttock.
He told the Daily Mail: “She'd had the Deathly Hallows symbol tattooed on it and she wanted me to admire it. It was very strange.
“Before she'd even said hello she came towards me, rear first, to show me this tattoo.
“Fans have no qualms about approaching you. And loads of them had tattoos. Some were quite good. But in one I looked more like Anne Robinson.”
