 In January 2015 , just prior to the broadcast of the episode " The Man Who Came to Be Dinner " , Al Jean and David Mirkin took to Twitter to reveal that the episode ( which had been produced in 2012 and was originally set to air on May 19 , 2013 ) had been held back because it was being " seriously considered " for adaptation into a sequel film as the episode was " very cinematic " ; they cited a similar sequence of events that occurred earlier in the show 's run with the episode " Kamp Krusty " . Jean also stated that he was sure reasons the episode both could and wouldn 't work as a film would occur to those that viewed the episode and later expanded that there was the fear of the potential film being considered " not canonical " with the TV series and the potential backlash of overcoming it by using a " memory wipe " .
