Charlie Hunnam has revealed he pulled out of the Fifty Shades Of Grey movie after suffering a "nervous breakdown" caused by his hectic work schedule.
The Sons Of Anarchy star was originally cast as male lead Christian Grey in Sam Taylor-Johnson's highly-anticipated big screen adaptation of EL James hit erotic novel last year, but quit just a few weeks later citing his "busy schedule".
Now the 34-year-old British actor, who was replaced in the role by Jamie Dornan, has opened up in an interview with The Moviefone Blog, revealing he became overwhelmed by the amount of work he had taken on.
Charlie explained: "I was going to finish Sons... at like 11pm Friday night, get on the plane Saturday morning to Vancouver for Fifty... missing the whole first week of rehearsal and start shooting Monday morning.
"And I was going to shoot that film, wrap that on the Wednesday and the following Monday I was going to start shooting Crimson Peak [Guillermo Del Toro's 2015 film] in Toronto. I just had like... Frankly, something of a nervous breakdown."
He went on "I just said, 'I can't... I can't.'
"To fail on such a grand scale - because Fifty's going to be massive, it's going to be huge. I really didn't want to fail on such a grand scale and I just couldn't transition from Jax Teller [his Sons Of Anarchy character] to Christian Grey in 48 hours. I bit off more than I could chew and it was painful. I loved the character and I wanted to do it.
"It was just a s*** situation. I was really, really, sorry to do it. It was one of those damned if you do, damned if you don't situations."
The Pacific Rim star also shot down rumours that he had pulled out due to creative differences over the script and concerns about being typecast.
He said: "I wouldn't have signed up in the first place if I didn't want to do it. It was a really, really difficult time in my life...
"And then I just fell in love, creatively. I started talking about this thing and I just got so excited. I fell in love with the character and started seeing him and becoming intoxicated, which is the way I work: I find a character I love and I start thinking about it all the time."
Charlie officially resigned from the role on October 12, 2013.
He later confirmed that his father had died shortly before.
"I have had some family stuff going on so I'm 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," he told E! News at the time.
