In 2008, Fernandez became one of the front-runners to play Edward Cullen after he auditioned for Catherine Hardwicke in her Venice Beach garage, during the casting of Twilight. Fernandez was allegedly Hardwicke's first choice, but it was up to Kristen Stewart who had the last say. Though he lost the Twilight role to Robert Pattinson, Hardwicke liked Fernandez enough to cast him in what would be his first romantic lead, in Red Riding Hood, opposite Amanda Seyfried. The role became his Hollywood movie breakthrough, making him a hot commodity. MTV Networks' NextMovie.com named him one of the "Breakout Stars to Watch for in 2011". As he shot into the spotlight, he was the cover model of Nylon Guys' March 2011 issue, introducing him as "Hollywood's New Rebel', and was the cover man for the April/May 2011 issue of Da Man magazine. In 2013, Fernandez starred in the remake of Evil Dead and in the independent film Syrup, based on the novel of the same name by Max Barry. In March 2015 Fernandez, earned one of the leading roles in the Canadian thriller film Edge of Winter, who wil star along Rossif Sutherland, Joel Kinnaman, Tom Holland, Percy Hynes- White and Rachelle Lefevre.
