Despite the glossy look and audience-friendly pacing, it's Hopkins and Gosling's charisma-duelling that provides the film's biggest reward. Apart, they're enjoyable enough, but when they get together to butt intellects -- with Hopkins at his most impish -- things really come to life. Given that Crawford is a rich, sneering murderer and Beachum is a swaggering money-hungry upstart, you'd be forgiven for wondering why you should care at all. This is, after all, an alienating world of elite high-rollers. Not even Rosamund Pike, as Gosling's highly-strung legal eagle love interest elicits any sympathy. But Hopkins and Gosling imbue their characters with such undeniable charm that you could actually end up rooting for either. Without the chemistry, you'd be left with a clever, well-crafted but ultimately empty thriller. It hides its final twist well, but the true triumph is in the casting. --Luke Mawson
