Matthew McConaughey and Woody Harrelson appeared together at the Los Angeles world premiere of Brothers, their new Apple TV comedy built around a fictionalized version of their friendship. The event took place at the Hammer Museum on September 17, ahead of the show’s September 23 debut.

Who joined them at the premiere?

Apple’s premiere photos also show Holland Taylor, Natalie Martinez and Brittany Ishibashi with the two leads. Taylor plays Ma Mac, Matthew’s mother in the series. Other cast members at the event included Nolan Almeida, Ella Grace Helton, Noah Carganilla, Highdee Kuan and Oona Yaffe.

What is the story behind Brothers?

McConaughey and Harrelson play versions of themselves whose friendship is shaken when Ma Mac lets slip that they might be brothers. Woody visits Matthew’s Austin ranch with his family while Matthew faces a separate identity crisis tied to a potential political run. The possible family connection is the show’s premise, not a confirmed fact about the actors’ real lives.

When does it premiere?

Apple TV scheduled the first two episodes of the eight-part comedy for September 23, followed by one episode each Wednesday through November 4. Lee Eisenberg is the showrunner and an executive producer; McConaughey and Harrelson also executive produce.
