The time has come. The "Friends" cast reunion will air on Sunday, Feb. 21, at 9 p.m. The show was created to honor sitcom director James Burrows who recently directed his 1000th television episode. Burrows directed 15 episodes of Friends.

While many of us were looking forward to seeing Jennifer Aniston, Courteney Cox, Matthew Perry, Lisa Kudrow, Matt LeBlanc and David Schwimmer on the same stage reliving fun times from the past, TIME reported Matthew Perry is unable to attend because he is rehearsing for his play, “The End of Longing.”
