Douglas 'humiliated' by physical demands of new film

Veteran actor Michael Douglas found shooting new movie The Sentinel "humiliating", because he couldn't keep up physically with his younger co-stars.

Kiefer Sutherland and Eva Longoria left the 61-year-old trailing during the shoot last year, and he confesses he felt his age.

"I had a bad knee and a pulled hamstring," said Douglas. "So it was tough - physically - and actually quite humiliating.

"In one scene, Kiefer takes off running and I go after him. I said to him: 'You're pretty fast' and he said: 'I had a state record in school for 400 metres.'

"Then later I'm running again and Eva passes me in high heels and I'm, like: 'How can she run like that in those heels?'."
