Brock said he prepared to get in any situation so that he was never confused during the fight. "After hitting him and knocking him down, I was like I gotta to get on top of this guy because I've seen him stand up and turn around and beat guys after he's been knocked down. I just had to seize the opportunity."

Lesnar said he was motivated by one thought. "If I get beat by a 45 year-old man, how am I going to explain myself?"

Lesnar also laughed at suggestions he should be in movies and said he's very happy doing what he's doing. "I really feel like this is where I belong"
