Actor Daniel Radcliffe is the latest star to lend his voice to the animated US programme The Simpsons. Dan will be spoofing the Twilight series, where he will play:

Edmund, a kid vampire whom Lisa falls for. Alas, Edmund’s father, a.k.a. Dracula, and Homer try to squash the budding romance.

“Daniel was very excited to do The Simpsons,” says Jean, “and we kept trying to ask him for secrets from the upcoming Harry Potter movie until we realized that they were all in the books.”

Dan's episode will air late next year, as part of the series' Halloween special, Treehouse of Horror XXI.
