Former “Fifty Shades of Grey” film star Charlie Hunnam spoke out for the first time since revealing he would leave the cast due to an inability to properly prepare for the Christian Grey role. There have been various rumors about why Hunnam left, including that he got cold feet and that he had issues with Universal Pictures over the script.

The “Sons of Anarchy” star cleared the air with E! News about his exit while appearing at the 2nd annual “Hogs for Heart” event, which benefits One Heart Source Education Programs in Africa, at Mo’s Restaurant in Burbank, Calif.

When asked how he was doing since leaving the movie adaptation of E.L. James’ novel, he replied, “I am doing good,” and added, “I am just really concentrating on work. It's been a really busy time.”

Meanwhile, Hunnam has faced personal issues. The star’s father, Billy, passed away in May. "I have had some family stuff going on so just trying to stay focused and stay positive and keep trying to do a good job at work and be with my family and stay positive,” Hunnam said.

The 33-year-old -- who is about to finish season 6 of the FX hit “Sons of Anarchy” -- dished about his plans for life after Jax Teller. "Like I said, I've got some family stuff I have to tend to. So when I wrap the show, I am going to go to England and see my people and then I have a film that I am doing with Guillermo [del Toro]. So I am going to go and do that and concentrate on the final seasons of Sons."

Dakota Johnson, who will play Anastasia Steele in the erotically charged film, is reportedly helping producers pick Hunnam’s replacement. According to producer Michael De Luca, a new actor to play Christian Grey will be selected within the month.
