Playing George Foreman in the biopic "Big George Foreman" was transformative, both physically and mentally, for actor Khris Davis. "This role changed me tremendously," Davis said. "Doing this role felt like an impossibility for me because how could I do the scope of this man in this short amount of time that I had to train, to then film?" In this "Salon Talks" interview, Davis talks about meeting the two-time world heavyweight champion and Olympic gold medalist, plus the physical demands that came with the role, including gaining 50 pounds in five weeks.
