London: Hollywood star George Clooney considered killing himself six years ago, after he injured himself while filming 'Syriana' in 2005.

The 50-year-old actor injured himself while filming the spy thriller and he was so racked with pain as a result of the spinal condition that he thought of ending his life, according to reports.

"I started to think, 'I may have to do something drastic about this'. I was in a hospital bed unable to move, having these headaches where it feels like you're having a stroke.

"You don't want to leave a mess, so go in the garage, go in the car, and start the engine. I was in a place where I was trying to figure out how to survive," he said.
