Look out, Robert Pattinson, because Daniel Radcliffe is about to trade in his wizard robes for some body glitter and an all-blood diet.
You can stop hyperventilating, Twilight fans: there are no plans for Harry Potter to take over Pattinson's part in Breaking Dawn. Instead, Radcliffe will spoof Twilight, lending his voice to The Simpsons for next year's ``Treehouse of Horror XX1'' episode. Radcliffe will play Edmund, a kid vampire who begins a relationship with Lisa.
``Daniel was very excited to do The Simpsons,'' executive producer Al Jean told Entertainment Weekly, ``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.''
Unfortunately for Lisa and Edmund, Homer doesn't approve of his daughter dating an immortal nightwalker, so the donut-loving dad vows to break them up. As luck would have it, Edmund's father - Dracula, obviously - wants the exact same thing, so the two disapproving dads join together to reach their common goal.
``Treehouse of Horror XXI'' will air in fall 2010.
