It's Very Clearly Stated In

I Try To Get The Best Performance An Actor Can Give.

I Make Films About Working Class People. All My Films Have Always Been About That. For Example, The Brothel Is A Workplace. It's Aberrant, But A Workplace Nonetheless. I Was More Interested As Opposed To Glamorizing And Saying, Oh, This Is A Great Erotic Place, It's A Place Of Business. The Commodity Is Sex.

But The Process Of Making A Film Is Not Glamorous. Certainly Not My Films.

Russell Crowe Is Very Difficult, But It's Worth It. He's The Real Thing. I Can Tell You This. Russell Crowe Was Just As Difficult Before He Was An International Star As He Was Afterwards.

Look At Walter Huston In The Devil And Daniel Webster: It's An Incredible Performance.
