"Friends: The Reunion" will debut on the WarnerMedia streaming service on May 27. (HBO Max is owned by WarnerMedia, which is also the parent company of CNN.)
Keep in mind that this is a reunion, but it's not a reunion episode. They will return to the show's original soundstage on the Warner Bros. lot "for a real-life unscripted celebration of the beloved show," according to HBO Max.
