Teenage actor Daniel Radcliffe hopes his world-conquering movie character Harry Potter dies at the end of author Jk Rowling's seventh and final book.

Rowling has one more book to write to complete her Potter saga, and Radcliffe is praying the finale will be the end of the bespectacled wizard.

He says, "I would like Harry to die at the end of that seventh book. I think it would be a very good ending.

"I wouldn't want it to be sentimental. I don't like sentimental ends to books or films. I think that would undermine the darkness the rest of the books have."
