Christian Bale refuses to condemn his late 'The Dark Knight' co-star Heath Ledger's hedonistic lifestyle.
Bale is famed for his clean-cut image, while Ledger's partying and addiction to prescription drugs has been well documented since his death earlier this year .
Bale refuses to criticise Ledger, insisting his exemplary acting skills outweigh any negative press.
He says: "He was a nice guy and out of this world as an actor. We got on and I never disapproved of his lifestyle. It's not up to one person to pass judgement on another person that way."
Ledger was found dead from an accidental overdose of prescription drugs at his New York apartment on January 22.
