Nicholson Productions released the video above with The Rock's father, WWE Hall of Famer Rocky Johnson, talking about his wrestling achievements and his boxing background. Johnson noted that he sparred with George Foreman and Muhammad Ali, and even turned pro for a short period.

Johnson also discussed racism in the business, which he said started dying out in the '70s. He claimed that Dick Murdoch was a member of the KKK, and said that he once knocked Murdoch out during a match.

"Because he [Murdoch] was KKK and didn't like blacks, he kept kicking me hard and punching me," Johnson said. "I said, 'you hit me one more time, I'm hitting you back.' He hit me, and I knocked him out."
