Christian Bale to lose weight again for Concrete Island

Christian Bale is expected to undergo another dramatic weight loss for his role in 'Concrete Island'.

The British actor will once again transform his appearance when he takes on the part of Robert Maitland, a wealthy architect who crashes his Jaguar on a manmade concrete island, surrounded by a motorway and has to survive on the contents of his car and anything else he can find in the psychological thriller.

Director Brad Anderson said: "I've got another project that Scott Kosar, the writer of 'The Machinist' is writing. It's based on J.G. Ballard's novel called 'Concrete Island'. It's an urban survival story that Christian Bale is attached to be in."

The 37-year-old hunk famously ate just a can of tuna and an apple a day in 2004 to drops 60lbs for his role in 'The Machinist' and more recently lost weight to accurately portray welterweight boxer turned cocaine addict Dicky Eklund in 'The Fighter'.

Although he has spoken of the "calming influence" of extreme dieting, Christian has claimed he would never lose as much weight for a role again as he did for 'The Machinist'.

He said: "I was the calmest mentally that I've ever been in my life. You just go beyond any bodily needs. Your energy gets to such a low point that it all just becomes mental. You felt like some sort of guru that could go sit on top of a mountain.

"Mentally, it does wonders, but I would never sacrifice the joys, the ups and the downs, the rollercoaster of life for that calmness. I'd rather be getting in there, getting involved and having it a bit more raw than that."
