Butler spoke previously about how difficult he found it to adjust when filming wrapped on the physically-gruelling action film 300.

He said: ‘When when you finish filming your whole routine changes and suddenly you don’t have to do what you did anymore. It’s kind of weird. You feel a little lost. You don’t have to hold yourself the same way physically.

‘I noticed in watching the video journals that even when I wasn’t performing, I was still walking around as the king and talking like him. I don’t do that anymore! I can slouch again!

‘There was definitely a period of adjustment and physical pain because I stopped training. That was the worst thing I could have done.’

It had also been reported last year that there were plans to make a sequel to the film, with claims in December that Joel Egerton was in line to replace Butler in the role of King of Sparta.

He was getting ready to film action scenes when he was thrown off his surfboard and pummelled by breakers at least 12 feet high, then held underwater for two consecutive waves before being hit on the head by four or five more when he managed to swim to the surface.

Speaking about the accident in January, Butler said: ‘It was a pretty close call.

‘The waves just took me in, and I couldn’t get up. It was pretty hairy. It was maybe of of the few times that reports were not exaggerated.’

Butler, who is a teetotal, also spoke previously about how he became addiction to alcohol.

He said: ‘I used to drink until I couldn’t remember anything. I was just mad for it and on a death wish. It was madness.

‘One or two drinks was never enough for me. I was a foot-on-the-floor-all-the-way drinker, so it had to go. I don’t miss it.’
