Homer loves you, his fans. He wants to answer your pressing questions and will do so in an upcoming segment on The Simpsons. Actor Dan Castellaneta will, as always, provide the voice of Homer immediately. The segment will be animated live, on the spot.
How? The Hollywood Reporter explains that the show will use motion-capture technology to automatically create an appropriate image of Homer interacting with his audience:
Showrunner Al Jean told THR that the series — which spends months prepping its animation — will use a motion capture technology in which Homer's voice and motions will be depicted in an animated scene talking about things he "could only be saying live on that day."
"As far as I know, this is the first time that's been done by any animated show," Jean said, noting the live bit works with the theme of the episode, which explores improv comedy. "And Dan is a great improviser."
