'Friends: The Reunion', hosted by James Corden, saw the show's famous cast, along with co-creators Marta Kauffman and David Crane and executive producer Kevin Bright, who shared a number of delightful behind-the-scenes tidbits from their time working on the NBC series, which ran from 1994 to 2004. Walking back onto Stage 24 at Warner Bros. Studios, the former castmates, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry, David Schwimmer and Aniston were taken aback by the site of meticulously recreated sets they hadn't visited in 17 years.
