Seeing Ace dealing with crooked gamblers was especially interesting. The parts of this film I enjoyed the most were when you learned about how Vegas operated. How and what happens to each you'll have to see for yourself.
Eventually, the pair end up having a downfall. Unlike Ace who had a veneer of honesty about him, Nicky was a hood.and didn't mind this. As for Nicky, as you'd expect with a Joe Pesci character, he's a bit of a nut-job.often out of control and letting anger govern most of his decisions. He was tough.but basically honest for a mobster. As for Ace, he was a smart man who was in charge of one of Vegas' top casinos. Sometimes Ace and Nicky (Robert De Niro and Joe Pesci) were in scenes together.often they were apart.each doing his own thing.
The film is unusual in that it has two leading men with parallel stories. However, despite being very violent in spots, the film turned out to be very was far more than just violence and had an interesting look at the mob influence in Las Vegas back in the day. I generally avoid violent films.which is why I resisted watching 'Casino' for a long time.
