Harry Potter stars 'should have rebelled'

Rex Features

Harry Potter star Jason Isaacs has admitted that he is amazed that the movie's young stars have never rebelled against their clean-cut image.

The actor, who plays the villainous Lucius Malfoy in the magical franchise, joked to The Daily Telegraph that the films might have been more interesting if the cast had a wild streak.

"The problem with Harry Potter is that there is so little controversy," he said. "It would be so great for the press if one of them would go off the rails and end up in rehab, but they are, actually, just really sweet guys."

Isaacs went on to praise the mentality of the leading actors, saying: "What is amazing about them is that they are still respectful and have humility and work ethic.

He added that they would never have to worry about their future because they "can fall backwards on their mountains of cash".

"It doesn't matter. They're really talented and they've got each other as close friends, which is all that matters because no one else has been through the same thing."

Harry Potter And The Half-Blood Prince is released in the US on July 15 and the UK on July 17.
