Harry Potter is trading in his wand for fangs.
Executive producer Al Jean told the magazine that Radcliffe will play Edmund, a young vampire that captures Lisa's heart. But Homer and Edmund's father, Dracula, try to break up the romance.
"Daniel was very excited to do The Simpsons," said 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."
Radcliffe's episode will air as a part of next fall's "Treehouse of Horror XXI."
