The upcoming Fox 25th anniversary special will spark nostalgia by bringing together some of the network’s most iconic shows and cast members.

The “Married… With Children” pilot will re-air, as will the 500th episode of “The Simpsons.” Fox will even bring on the casts from “In Living Color,” “That ’70s Show” and “Married… With Children” for a reunion.

The Fox 25th anniversary special will take place on Sunday, April 22 beginning at 7 p.m. Some of the actors who have been confirmed to appear on the show include Calista Flockhart, Shannen Doherty and her “Beverly Hills, 90210″ cohorts, Katey Sagal, Ed O’Neill, Christina Applegate and David Faustino; and “The X-Files” stars Gillian Anderson and David Duchovny.
