Radcliffe, who rose to fame playing the child wizard, was surrounded by bodyguards and police, but that did not stop some admirers pushing their way into the bathroom with him during a press conference break.[break]
The 24-year-old shrugged off suggestions that the clamour of hyperventilating teenagers on Venice´s picturesque Lido island was intimidating.
"Thankfully, it´s not always like this," he told the press conference, as a crowd outside thumped on the walls and rattled the windows trying to get in.
"I´ve been dealing with it in various ways since I was 11. I don´t take it seriously, actually I think it´s funny," said a smiling Radcliffe, sporting a blue polo shirt, rainbow-coloured socks and pastel pink sneakers.
The actor -- with his parents in tow -- may be an A-lister, but he still has a schoolboy air, and rather than the usual cocktail soiree held to honour Venice stars, he has requested a Karaoke party.
Radcliffe was in Venice to present "Kill Your Darlings", a Beat Generation film by John Chokidars, in which he plays a young Allen Ginsberg.
He said he thought fans would enjoy the flick, which explores themes from drug use to homosexuality.
"I´m incredibly grateful for the swirl of support behind me. My fans seem excited by the unconventional path I am taking," he said.
"I love poetry and it was fantastic to get the part and have the opportunity to dive into Ginsberg´s life. The diaries he made when he was young gave me an amazing insight into his character," he said.
For fans of "A Young Doctor´s Notebook", a television series starring Radcliffe as a doctor forced take up a post in a small, remote hospital in Russia, the actor promised "series two is funnier and even darker."
