Tom Cruise had to dig deep for his latest starring role — pun intended.

“I have never had something that could challenge me in this way, and neither has Alejandro,” Cruise said, about starring in “Digger,” the black comedy from two-time Academy Award-winning director Alejandro González Iñárritu.

Described as “a comedy of catastrophic proportions,” the Warner Bros. film is Iñárritu’s first English-language film since “The Revenant.” Cruise stars as Digger Rockwell, sporting a thick Southern accent, a pot belly and thinning white hair (fashioned in an unconvincing combover) to play the oil baron (“the most powerful man in the world”) whose company may have set off an ecological disaster that could also spark a nuclear war. As the logline teases, the film follows as Digger “embarks on a frantic mission to prove that he is humanity’s savior before the disaster he’s unleashed destroys everything.”

John Goodman portrays an ailing U.S. president who implores Cruise’s character to fix the mess he’s unleashed, while Sandra Hüller, Michael Stuhlbarg, Jesse Plemons, Sophie Wilde, Riz Ahmed and Emma D’Arcy round out the buzzy ensemble cast.

Ahead of the trailer’s launch, Cruise previewed the highly anticipated footage for press, film critics and fans in a special presentation on the Warner Bros. lot in Los Angeles.
