The breadcrumbs leading to a close encounter are more contemplative than candy-coated in Steven Spielberg’s latest: if we were luring E.T. himself into the action, it would be done here with a bag of Reese’s Thesis. Spielberg has a lot on his mind, and his Disclosure Day (B) exports many of his deep thoughts to celluloid with a smash-up of paranoid thriller and existential essay. Without spoiling the plot, suffice it to say the  director is interested in knowing if today’s global population of human beings could contemplate, agree on or even properly behold a miracle coming true in the modern world. All aren’t created equal in the film’s ensemble, with Emily Blunt standing head and shoulders over her cast mates as a news personality recently obsessed with perpetual movement toward a singular life event. As a tech expert outrunning the secrets of his sinister former employer, Josh O’Connor is on a similar trajectory toward something leviathan; his part is just less showy and interesting. Much of the movie’s first act is preoccupied with tracking down characters’ locations and leaving the viewer pondering myriad questions; but by the final act, the hot take gets cooking. There’s a propulsive, talky way of getting at some major interconnected issues, with a few magnificently staged chases including one with a crashed car attached to a moving train providing a rousing respite from all the speculating. There is an underdeveloped character (Colman Domingo) assembling others to some sort of makeshift sound stage and a stock villain (Colin Firth) who ultimately doesn’t have much to do aside from, again, finding peoples’ locations. Much of the plot could be curtailed with a good GPS! But by the time the director goes for the big swings about one of his lifelong cosmic preoccupations, he largely sticks the landing. Some action sequences feel long jn the tooth, and the intellectual passages don’t all necessarily pay off. Blunt makes the most of it all as a woman possessed; all the best sequences in the film involve her surreal journey. Wyatt Russell as her love interest is delightful and underused in a flash of comic relief and relatability. John Williams provides workmanlike music for this outing, and the effects are good but not great, with a throwaway line nearly apologizing for the rendering of some of the animal effects.  Janusz Kamiński’s cinematography is stunning; there are lots of sequences with characters reflected together through glass which deepen connections and help themes to gel. Despite many great elements, the film is ultimately a prelude to a great conversation rather than a masterpiece in and of itself.
