While filming “Emancipation,” Will Smith routinely drew inspiration from the words “sacred motivation” that were written on the front page of a script. But the Oscar winner heavily leaned on the phrase even more in recent months, as he tried to overcome the backlash to his Oscars slap and banishment from the ceremony.

“It’s like when you can locate and center yourself in your divine purpose, you can withstand anything and everything,” Smith said of the phrase that greeted him when he took on the lead role in Antoine Fuqua’s “Emancipation,” which is currently in theaters and will be available to stream Friday on Apple TV+. “Sacred motivation” became like a theme for him and his castmates, Smith said.

The film, completed months before Smith strode onto the Oscars stage and slapped presenter Chris Rock for a joke about Smith’s wife, Jada Pinkett-Smith, was a grueling shoot. Inspired by an iconic 1863 photo of the scarred back of “Whipped Peter,” Smith portrays the character Peter — a man who attempts to escape slavery while he uses his wits to dodge slave hunters and brave alligator-infested Louisiana swamps in his quest for freedom.

The photos of “Whipped Peter” were taken during a Union Army medical examination that first appeared in Harper’s Weekly. An image known as “The Scourged Back” showed countless mutilated whip marks on Peter’s bare back that were delivered by his enslavers. The photo contributed to the growing opposition to slavery.
