Matt Nable never intended on becoming an actor. In fact, he was a professional athlete for most of his early 20s, having played for two high-profile Australian rugby teams, before retiring from the sport to become a writer. Like most newbie authors, Nable wrote about what he knew, eventually turning his experiences on the rugby field into the screenplay for the 2007 sports drama "The Final Winter," which he also starred in. Although the film failed to find an audience, it showcased Nable's talent as an actor - a skill he never knew he had - and in the years that followed, he began making a name for himself playing tough-guy roles in big-budget action movies such as "Killer Elite" (2011) and "Riddick" (2013). Nable may have never set his sights on acting, but by 2013 he was proving to the Hollywood establishment just how talented he was at it.
