Director David Leitch builds a better mousetrap out of the snatch-and-grab genre on a modern-day Orient express in the Tokyo-set anything-goes action yarn Bullet Train (B). Fond homages to Kill Bill and The Warriors abound as a rogues’ gallery of antiheroes assembles aboard a speeding locomotive with vengeance embedded in its steam-pipe ethos. With unusual chronology and flashes of back story, it becomes clearer why the ensemble is aboard the vehicle. Brad Pitt is the zen protagonist imbued with super-chill talents of snark and imaginative stunt choreography in equal doses; it’s fun to watch a reformed assassin in progress as he quietly observes the folly of his ways to Sandra Bullock in an earpiece while clashing with the cavalcade of obstacles in his way. Aaron Taylor-Johnson and Bryan Tyree Henry are among the most amusing denizens of the whistle-stop whirling dervish, a droll duo with killer banter. As an elder with manga and martial arts magnetism, Hiroyuki Sanada is another effective standout in the star-studded cast. Leitch unleashes a blood splattered bubblegum hued environment with endless invention, the kind that surprises, delights and sometimes wears out its welcome. Overall it’s gonzo action-packed fun, though, with surprises around every turn.
