But RDJ doesn't alter his style often in the characters he plays. For example, he's the same in US Marshals as he is in Iron Man. The Soloist too, completely different character but same delivery. He is RDJ, not Iron Man/Stark. You have to like RDJ in order to like Iron Man, because its a film about RDJ posing as Iron Man, not simply a film about Iron Man. Whereas look at Cavill in The Cold Light Of Day. It is an action role, yet his style of delivery is absolutely opposite to Man Of Steel. RDJ's delivery doesn't vary, whereas.
