In "Walking Tall," former pro wrestler Dwayne "the Rock" Johnson plays a man who returns to his hometown only to find things aren't quite the way he left them. So he gets his hands dirty while cleaning up the corruption, and he brings along "Jackass" star Johnny Knoxville for a little help and some comic relief. As the tattooed action star explained to MTV News' Ryan J. Downey, Knoxville's antics weren't limited to what was spelled out in the script.
MTV: How do you think Johnny Knoxville did in this movie, especially doing those stunts? I would imagine everyone would be like, "Oh, you're the 'Jackass' guy."
The Rock: He did great, and he had a stunt double. And to his credit he was like, "Nah, no way, no stunt double!" And that guy, he was getting his ass whooped and still got up with a smile and was like, "Let's just do it again." Plus I expected that from him. I spent a lot of time with him anyway prior to us filming, so I knew. You know, you gotta be a little tweaked and twanked a little bit if you're Johnny Knoxville, and he did an awesome job.
MTV: Did he crack you up on the set?
The Rock: Oh yeah. Yeah, well, that's the thing. You know, we'd be in this scene together and it's somewhat of a dramatic scene and he's telling me, "Listen, I went to jail, I was on drugs" and things like that. And I'm trying to listen to him, and until right before the director would yell "Action!," Johnny would be eating something crazy like tuna fish and peanut butter or sour milk and who knows whatever else
