Charlie Hunnam, who plays protagonist Jackson "Jax" Teller in FX's "Sons of Anarchy," recently discussed leaving the upcoming film adaptation of E.L. James' bestselling "Fifty Shades of Grey" series.

Just a month after he was cast in forthcoming movie, the 34-year-old British actor made a quite difficult decision to drop the lead male role of tormented 27-year-old billionaire Christian Grey due to his demanding shooting schedule with the hit outlaw motorcycle club series and family issues.

Hunnam admitted that it was "heartbreaking" for him to give up his film role. "I felt like I had an interesting take on that character and felt like I could have done a good job of playing Christian Grey, otherwise I wouldn't have taken it on in the first place," he said.

"When you put the time into something like that and a character comes alive in your mind, it's heartbreaking not to be able to play him," he added. "It was definitely kind of heartbreaking having to say goodbye to that character and not bring it to life."

It was confirmed last September that Charlie Hunnam "Grey" would be replaced by Irish actor Jamie Dornan, who is known for his portrayal of a serial killer in Ireland's television series "The Fall." When asked what he thinks about his replacement, Hunnam claimed that he is not familiar with Dornan's work but assured fans that director Sam Taylor-Johnson will do a great job.

Now that the "Fifty Shades of Grey" movie is done with its production, the "SOA" actor plans to fully support the film when it hits theaters next February. "If they invite me to the premiere, I will go and see it there," he said. "If not, I'll go and buy some tickets on opening night."

Meanwhile, Hunnam was at Huading Film Awards ceremony in Hollywood to be honored for Best Global Emerging Actor for his outstanding performance in the popular biker series as well as in "Pacific Rim," voted by 80 million Chinese fans all over the world.

The upcoming highly-anticipated Season 7 of "Sons of Anarchy" will return on FX in September.
