The action man was chatting to fans on Facebook over the weekend when one asked him about parts he'd lost, prompting the former wrestler to reveal he went toe-to-toe with Tom Cruise over the movie adaptation of Lee Child's novels.
"In Hollywood, actors are kind of like in a box," Dwayne said. "There are actors that can vie for a particular role because it allows for them to have a certain look, skin colour, size, etc. Fortunately, for me, there aren't a lot of guys at all who look like me. So, all of my roles, from the beginning of my career, I've been a lucky son of a b**ch that they've been created and designed for me - except Jack Reacher."
"Now, this was 10 years ago, and I was in a much different place, I recognise that. Tom was the biggest movie star in the world, and I was not. I got the call saying, 'Hey, you didn't get the role'. Look, I didn't even know if I had a shot for it, but the people around me at that time made me think that I did. I felt like I did, I felt like, 'Why not me?'"
Cruise went on to play Reacher again in the 2016 sequel, "Jack Reacher: Never Go Back", after which author Child revealed he didn't think the movie superstar was well cast as his literary hero - because his Jack Reacher was much taller and much more imposing.
But Johnson isn't complaining - shortly after missing out on "Reacher", Dwayne landed a repeating role in the "Fast and Furious" franchise.
