The Watch Passenger 69 XXXRock might seem like an obvious Hollywood action hero success story now, but even hehad moments when the world doubted him, and he shares some of that struggle in a brief Instagram video he posted on Sunday.

But The Rock isn't alone, also appearing in the video are NFL star Cam Newton, NBA champion Kevin Durant, and Mashable'sown founder Pete Cashmore, among others.

They all tell brief parts of their stories of defying the odds to achieve success in a promotional video for the four-part HBO docu-series called The Defiant Ones. When it comes to The Rock, when he met doubt about his prospects in Hollywood, sports, and pro wrestling, he simply said, "Fuck that." (Remember that steely resolve the next time you see him flash that warm, mainstream-friendly smile.)

The series itself focuses on the rise of Jimmy Iovine and Dr. Dre as they built a music business empire, long before they earned their way in executive seats at Apple through Beats.

The list of celebrities appearing in the series is long and impressive, including Bruce Springsteen, Kendrick Lamar, Sean "P Diddy" Combs, Eminem, Gwen Stefani, Patti Smith, Tom Petty, and many others.

Directed by Allen Hughes (Menace II Society, American Pimp), the film series made its debut on Sunday and will air a new episode every night until July 12.
