1st look at 'Friends' cast back together for upcoming 'The Reunion Special'

HBO Max revealed Thursday that its long-awaited "Friends: The Reunion Special" will air May 27.

The new teaser just shows the cast -- Jennifer Aniston (Rachel Green), Courteney Cox (Monica Geller), Lisa Kudrow (Phoebe Buffay), Matt LeBlanc (Joey Tribbiani), Matthew Perry (Chandler Bing) and David Schwimmer (Ross Geller) -- walking on the Warner Bros. lot together and shot from behind in slow motion.

As a lilting version of the show's theme song -- "I'll Be There for You" by The Rembrandts -- plays, a title card reads, "The One Where They Get Back Together."

Meanwhile, the streaming service revealed the special will include a slew of special guests, including David Beckham, Justin Bieber, BTS, James Corden, Cindy Crawford, Cara Delevingne, Lady Gaga, Elliott Gould, Kit Harington, Larry Hankin, Mindy Kaling, Thomas Lennon, Christina Pickles, Tom Selleck, James Michael Tyler, Maggie Wheeler, Reese Witherspoon and Malala Yousafzai.

Of course, many of those names will be familiar to "Friends" fans, such as Gould and Pickles, who played Ross and Monica's parents; Selleck, who played Monica's long-time flame Richard; Wheeler, who played Chandler's on-again, off-again girlfriend Janice; Witherspoon, who played Rachel's sister Jill; and Tyler, who played "Central Perk" mainstay Gunther.

The "Friends" actors will reportedly appear as themselves, not their characters, for what HBO Max calls, "a real-life unscripted celebration of the beloved show."
