After making his mark in the small screen on his hit TV show "Sons of Anarchy," Charlie Hunnam made some headlines last year when he walked away from a titular role in the movie adaptation of "Fifty Shades of Grey." Biting off more than he can chew, the actor pulled out on the last minute and revealed that it was one of the toughest decision he had to make.

"It was very painful and it was very difficult. I was worried that the wrong perception would come out, which is what happened-it was all about that I got cold feet, or that I didn't have faith in the movie, or that I didn't like the script, and all this f-king bulls-t," said the 34-year-old hunk in an interview with Entertainment Weekly. "I just kind of made a bit of a rookie mistake in that one in biting off more than I could chew."

After going radio silence, the British star revealed how he got through the media storm about his decision to pull out from the role as Christian Grey and giving his word to director Sam Taylor-Johnson. More than the public scrutiny of backing out from the highly-anticipated film, the actor was dealing with emotional crisis and even had a nervous breakdown from juggling his time with so many projects.

Currently filming the last season of his biker drama series, the "Crimson Peak" star was spotted last Tuesday, Sept. 30, as he sweats out on the show's L.A. location set. Filming some scenes with his hot leather waistcoat, Hunnam looked very much in character as SAMCRO's president Jax Teller with his white T-shirt and baggy pants.

The L.A. sightings was two days after he was spotted spending some time with his biker friends in West Hollywood. Hunnam was seen chatting with some friends after driving away with his Harley Davidson last Sunday.

With more than seven million followers of the show, the "Sons of Anarchy" lead star is scheduled to have two nude scenes in the upcoming episodes. Something that female "Sons of Anarchy" fans are looking forward to.

"Sons of Anarchy" season 7 is aired on FX every Tuesday at 10 pm.
