Cyberthreats were named the number one danger to the US last year, and the movie Blackhat explores exactly why that is. The film is about a hacker who blows up what appears to be a nuclear reactor and then begins to wreak havoc elsewhere across the globe — which is basically what actual governments are concerned about worldwide. Chris Hemsworth stars as the titular black-hat hacker who the US government calls on to help fight the threat. While a cybersecurity battle that, somehow, also involves a lot of gunplay could turn out a little goofy, the movie has Michael Mann behind it, and he has plenty of crime thriller experience with big movies like Heat and Collateral. A new trailer for it was just released today, ahead of the film's release in theaters on January 16th.
