New Delhi, Sept. 21 -- Hollywood star Dwayne Johnson has spoken about stepping into one of the most demanding roles of his career, in the upcoming film 'The Smashing Machine'.

Johnson, best known for his work in action and adventure blockbusters, said the chance to play a raw dramatic role was something he had been waiting for.

"For years, I've been dreaming and hoping," he explained, in a recent CBS interview. "My desire was to play not only a dramatic role, but something that I felt like I could really sink my teeth into, and rip myself open. You hear that term. I just didn't want to do drama. I wanted to do something that really allowed me to do that."

The film, directed by Benny Safdie, sees Johnson star as former mixed martial art...
