In an episode airing this coming season, Bart will encounter Diggs (Radcliffe), a strange older boy with a passion for falconry, among other things. “Diggs is a combination of Holden Caulfield, Finny from A Separate Peace and the kids in Lord of the Flies — only a little more screwed up,” executive producer Al Jean tells EW.

Why did the producers bring him back? “I had the pleasure of meeting him after one of his performances in How to Succeed in Business Without Really Trying, and he is one of the people who actually listens to Simpsons DVD commentaries,” quips Jean. “Also, he was terrific.”

Update: 8th January 2014. Fox announced that Daniel's second The Simpsons guest voice episode called Diggs is set to air 9th March 2014.
Update: 23rd January 2014. The first still is released featuring Daniel's charater Diggs which was posted on Daniel's Google+ page.

The 25th season will begin airing on Fox on September 29, 2013.
