According to the On the Red Carpet:
‘The Simpsons will be taking on The Twilight Saga in their annual “Treehouse of Horror” Halloween episode and Harry Potter star Daniel Radcliffe will be voicing a vampire named Edmund.
Fans can see a glimpse of what Radcliffe’s character, a vampire named Edmund, will look like in art released by Fox (seen right).
In “Tweenlight,” which is a short in the episode, Lisa Simpson falls for the new vampire student.“Daniel was very excited to do The Simpsons,” exec producer Al Jean told Entertainment Weekly in November 2009, “We kept trying to ask him for secrets from the upcoming Harry Potter movie until we realized that they were all in the books.”

Twilight Poison found the official summary from Fox:
THE SIMPSONS (8:00-8:30 PM ET/PT) – “Treehouse of Horror XXI”
The supernatural spells continue in “Tweenlight,” when Lisa (Yeardley Smith) becomes smitten with a mysterious new student, Edmund (guest voice Daniel Radcliffe), who also happens to be a vampire. When a romance blossoms, the young lovers run away to Dracula-la Land, leaving Homer (Dan Castellaneta) to come to Lisa’s rescue.
It will be interesting to see who else goes the Twilight themed Halloween route. Last two years The Office has had Twilight elements in their Halloween and Christmas shows.



Shouldn’t it be ‘seen left’ and not ‘seen right’?
I can’t wait for this episode!
Apparently, Supernatural on the CW is also having a twilight themed episode called ‘Live Free or Twi-hard’ with vampires named Rob and Kristen.
Yes! I LOVE Harry Potter and Daniel Radcliffe of course <3
Too funny…I will actually watch the Simpsons to see this one. I love Edward Cullen AND Harry Potter!!!
Me too cant wait to check it out, “Treehouse of Horror” is always my favorite episode of their season.
Oh dear. I can hear the HP fans getting riled up as we speak!

I love The Simpsons and Twilight and Harry Potter so this is going to be a treat for me. I wonder how Edmund will sound like. LOL
I Can’t Wait!
I have been waiting all year for this episode of the Simpsons,when it was first announced that Daniel Radcliffe would voice the parody. I’m a huge Simpsons fan so this is an added bonus for me,since I’m also a Twilight fan as well.Can’t wait to see Edmund and Lisa fall in love and Homer try to stop them. LOL!
I agree with Twilight Nymph I love The Simpsons, Twilight, and HP so this will definitely be on when it airs!
