Kiwi born Hollywood star Russell Crowe has played many intense roles in his career. 

But his latest might be his most intense yet. 

Heading back to world war 2, Russell plays Hitlers right hand man Hermann Goring in ‘Nuremberg’, the film focusing on the duel between psychologist Douglas Kelley and Goring, in the lead up to the post war trial. 

Crowe told Francesca Rudkin that he had to do a lot of background reading before playing the part. 

'So you have to find those moments of what I call quiet contemplation, where you get to really think through and learn about what you're doing.'
