The official trailer has dropped for the George Foreman biopic, titled “Big George Foreman: The Miraculous Story of the Once and Future Heavyweight Champion of the World,” from director George Tillman Jr. It explores the life of the legendary boxer turned minister. Forest Whitaker portrays Doc Broadus, the boxer’s longtime trainer who introduced him to the sport, while Khris Davis will portray Foreman.

The biopic will follow Foreman’s boxing career highlights, including when he obtained Olympic Gold at the 1968 Mexico City Games and his world heavyweight champion run. Outside of his boxing career, the narrative will cover Foreman finding his faith, retiring and becoming a preacher.
