Brad Pitt, whose most embarrassing moments in “Bullet Train” (like getting sprayed in the face with a bidet or losing his train ticket within minutes) is made just an ounce less cringe by the coolness factor afforded to him by a stylish outfit — namely, a floppy white bucket hat and wide-rimmed glasses that remain his staple accessories throughout most of the film.The first time you see Pitt without the floppy headwear is when it’s forced off him while in a showdown against Bad Bunny in a desolate train cabin (Bad Bunny is one of the first casualties as half a dozen assassins attempt to kill each other on board the bullet train from Tokyo to Kyoto to get their hands on a briefcase full of cash). Once Lady Bug successfully stabs him in the heart and cleans up the mess, he swiftly puts the hat back on, not a single blood stain to be seen.
