It's hard to imagine the current television landscape without FOX and yet the network that gave us 'The Simpsons,' 'The X-Files' and yes, 'Who Wants to Marry a Millionaire,' is only twenty-five-years old. And to celebrate its quarter-life crisis, FOX has brought together the casts of the seminal shows that made it a success.

The stars of 'That 'That '70s Show,' 'Beverly Hills 90210,' 'In Living Color,' 'The X-Files,' 'Married with Children' and interestingly, 'Arrested Development' gathered together for what the network describes as "an historic look back at the groundbreaking and irreverent shows that have defined the network since its first signal transmission on April 5, 1987."

While it appears the TV-turned-movie stars who careers the network helped launch like Jim Carrey ('In Living Color') and Johnny Depp ('21 Jump Street') weren't on hand, FOX did manage to wrangle 'Californication' star, David Duchnovy, 'Modern Family's' Ed O'Neill and 'Two and a Half-Men' savior, Ashton Kutcher.

Unfortunately, it looks like neither Rick Rockwell nor Darva Conger were available to celebrate their particularly dark time in FOX history. The two-hour special airs Sunday, April 22nd at 8PM ET/PT. Check out behind the scenes photos from the all-star gathering below!
