The release of one of the most eagerly anticipated TV reunions ever has sent fans around the world into a Friendzy.The hugely popular US sitcom, which followed a group of New Yorkers in their twenties and thirties, concluded in 2004 after 10 seasons. Seeing all six principal cast members get back together to discuss their time on the show is genuinely rare. In recent years, journalists have generally been told not to ask any Friends questions when interviewing the show's former stars. Read more below!
3. Fake Joey was almost Real Joey
Creators Kauffman and Crane and director Kevin Bright share many behind-the-scenes stories. Friends scholars will have heard many of them before, like how Cox originally auditioned for Rachel before being cast as Monica.
But there are some new nuggets here too. Bright recalls the tough audition process for casting Joey. He says it "went down to the wire" with LeBlanc and another actor.
"But the funny thing about it is the other actor ended up in the show, in The One With Unagi. Playing Fake Joey, ironically."
That means the other actor in the running was Louis Mandylor, who appears in the season six episode as part of a plot line where Joey is trying to earn money by pretending he has an identical twin.
2. Friends: The Movie?
It isn't easy for a series to maintain razor-sharp writing, relatable characters, well-observed storylines, great on-screen chemistry and high viewing figures for 10 years. But Friends did it - and without ever jumping the shark (although it came pretty close in season nine, with a weak episode literally titled The One With The Sharks).
Fans of the US sitcom often say, only half-jokingly, that every situation in life can be related to a Friends storyline. And while some sections of this reunion do feel a little padded out, ultimately this is a classy and enjoyable special which won't disappoint devotees.
For years, many fans have been desperate for a scripted reunion - with the stars reprising their roles in a new series or film. But you can guess how the cast react to being asked by Corden whether they've considered it.
"No. I'm sorry, I haven't,"
says Kudrow. "I once heard Marta and David say, and I completely agree, that they ended the show very nicely, everyone's lives are very nice, and they would have to unravel all those good things in order for there to be stories. And I don't want anyone's happy ending unravelled. Also, at my age, to be 'floopy'? Stop. You have to grow up."
1. There's no shortage of celebrities
Some celebrities get heavily involved in the games and activities. We won't spoil those here but there's an extremely special guest duetting with Kudrow on Smelly Cat. Other stars simply appear briefly to share the influence Friends had on their lives.
"My mum bought me the DVDs of the whole series when I was in elementary school, Friends really had a big hand in teaching me English."
explains RM of Korean boyband BTS.
Meanwhile, Nobel Peace Prize-winner Malala Yousafzai reveals she has a soft spot for The One With The Routine, comic Mindy Kaling likes The One with All The Kissing, and actor Kit Harington particularly admires the "pivot" sequence in season five - where Ross, Chandler and Rachel are trying to get a couch up the stairs.
"I'd have to say I'm most like Monica, because I'm a clean freak,"
reflects footballer David Beckham. "I travel a lot, I'm always in hotels, I've always got down time, when I'm missing the kids, missing the family, I put on Friends, because it makes me smile."
