Swank film tests McGregor's smoking ban

Ewan McGregor faced the ultimate test in his bid to quit smoking for good when he was asked to pick up the habit again for a film role.

The Scottish actor gave up cigarettes in 2007 and admits he has often struggled to stay "clean", but it was his role opposite Hilary Swank in 'Amelia' which really proved he's a determined ex-smoker.
