Here we have the first trailer for Michael Mann’s Blackhat, the Heat director’s first film since 2009’s lukewarmly received Public Enemies. Observe Chris Hemsworth as a hacker who enters government service to battle some really dangerous high-level computer shenanigans. The trailer plays adroitly on contemporary paranoia about the real-world fallout of technological malfeasance, and there’s gunplay galore in the director’s trademark digital-blur-at-night idiom. The vibe and visuals are very much in keeping with Mann’s 2005 update of his Miami Vice, complete with Hemsworth’s slicked-back, Colin Farrell-esque hairdo, though the music — Antony & The Johnsons covering “Knockin’ on Heaven’s Door” — is a definite step up from the director’s usual Audioslave pocket of sludge. The Trip to Italy fans: I regret to inform you that the joke of Rob Brydon being part of the cast is apparently merely a joke.
