Dwayne "The Rock" Johnson has landed a massive success with his most recent film, The Smashing Machine. The Rock's transformation into UFC and MMA Legend Mark Kerr allowed him to step away from his usual action or comedy flicks and jump into a genuinely dramatic role. And Dwayne Johnson recognizes how important this one could be to his Hollywood legacy. The Smashing Machine is based on the 2002 documentary, The Smashing Machine: The Life and Times of Extreme Fighter Mark Kerr, and has received rave reviews since the early screenings back in September. It currently sits at 73% fresh on Rotten TomatoesThe Rock isn't taking this one for granted. In an Instagram post, he thanked everyone who watched The Smashing Machine, as well as his director, before recognizing that this movie may have completely changed his life.

In our storytelling world, you can't control box office results - but what I realized you can control is your performance, and your commitment to completely disappear and go elsewhere. And I will run to that opportunity. It was my honor to transform in this role to my director Benny Safdie @bowedtie. Thank you brother for believing in me. Truth is this film has changed my life. With deep gratitude, respect and radicalempathy, dj." -The Rock on InstagramThe Smashing Machine was released on October 3rd in the United States. Unfortunately, box office numbers were lower than expected, partly due to the release of Taylor Swift's Showgirl.What's next for The Rock? Dwayne Johnson has already built up an incredible name outside the ring. It's been 24 years since his debut film, The Mummy Returns, and The Great One is now well over fifty films into his career. With the Mark Kerr biopic receiving high praise, Johnson will have time to soak up and appreciate the response for a while before promoting his next film.
