The Simpsons / Family Guy crossover episode, first announced last week, is expected to air as an hour-long special in 2014. Just following the announcement of the Simpsons / Futurama crossover episode, New details of the special episode were revealed at Comic Con 2013 by Rich Appel, currently a co-exec producer on Family Guy and formerly a producer on The Simpsons.
[The crossover is] gonna be the season premiere in a year, but it's a super-sized episode - it may be an hour episode," said Appel.
"We were thrilled - [The Simpsons voice actors] Dan Castellaneta, Julie Kavner, Hank Azaria, Yeardley Smith, Nancy Cartwright... they all play their parts."
"As soon as Dan opened his mouth with his first Homer line, there was a wave of applause," Appel said of the first script read-through.
"[And] there may or may not be a 5-minute Chicken fight between Peter and Homer!"
As mentioned earlier, The Simpsons will also crossover with another Matt Groening creation - animated sci-fi comedy Futurama - in an upcoming episode.
