The promise of seeing Scarlett Johansson fully nude is probably enough to lure lots of people into Jonathan Glazer's alien-among-us fantasy Under the Skin, and the vision doesn't disappoint: Her figure, seen in long shot, is a grand and glowing thing; she has one of those butts shaped, adorably, like an upside-down heart. But her nakedness is the opposite of a sleazy thrill. As Glazer presents it to us, an Eadweard Muybridge nude miraculously come to life, it's so unadorned and purely human that it's entrancing on a whole other level. That Johansson's character is not human at all only adds to the pathos, and the terror, of it all. She is, as we learn early on, a killer from another world masquerading in womankind's touch-me skin. In her nakedness, she hides everything and nothing; she's treachery and softness rolled into one.
You could say the same of Under the Skin itself, a science-fiction rhapsody laced with thorns. Adapted — though maybe "morphed" is a better word — from Michael Faber's 2000 novel of the same name, this is the story of a girl who fell to Earth, or who was, perhaps, put here to do a job. The exact motivation of Johansson's character is never made clear, though she seems to be harvesting male flesh for either herself or her race. Really, very little in Under the Skin is clear at all. Its secrets unspool in mysterious, supple ribbons, but that's part of its allure, and its great beauty. This picture is often mesmerizing and sometimes almost unforgivably cruel: The image of an infant crying on a cold, savage beach appears onscreen for just a few seconds, though it takes much longer to shake it off. But if Glazer is only just resurfacing with his first movie in ten years (the last was the 2004 arty-elegant reincarnation romance Birth), at least he's coming back with a great one. Along with his actors, cinematographer Daniel Landin and composer Mica Levi, he's made a work of quiet audaciousness, half-soothing, half-jolting. This is a dream-state movie that's always fully awake and alive.
Johansson's character has no name, and though she speaks in a reasonably proper English accent, she seems to have come from nowhere. This enigmatic creature, with her short crop of dark curls and mischievous half-moon of a smile, drives around Scotland's bramble-gray countryside and its chattery, bustling cities, using her sexual magnetism to lure men to their doom. She wears everyday mall clothes — skinny jeans, a faux-fur jacket — and banters casually with her marks to determine how much they'll be missed by anyone at home, or if they'll be missed at all. They're all regular guys, sporting jerseys of their favorite football teams, some of them rabbiting on in such thick Scots that they may as well be speaking the language of another planet. Our alien beauty leans in close to hear what they're saying, to determine if they'll suit her purposes. Some of them immediately remark on how pretty she is; others seem to avoid even looking at her before stumbling to tell her they find her attractive.
What Johansson is working here is "glamour" in the original and ancient sense of the word, not the Hollywood one, a point brought home by Glazer's working methods. Most, though not all, of the men in the film are non-actors, unaware that they're being chatted up by a bona-fide movie star, the proceedings captured by a small hidden camera. On the surface, at least, it's an approach that invites some moral queasiness: Even though all of these "performers" were clued in after the fact, and signed the required release forms, it doesn't seem right to make human beings the unwitting pawns of movie artistry. But I think the way Glazer uses these performers is ultimately respectful. We're on their side — we can't blame them for falling for this not-quite-Scarlett Johansson, because we've fallen, too. Watching them respond to alien Scarlett is fascinating; some of them are so shy they seem reluctant to look at her directly. But watching her coax them into her net is the real wonder here. When she's being observed only by us, the character's stare is simultaneously hungry and blank. When she's working her wiles, her eyes are bright and reflective: "I'm far more interested in you than I am in myself," they seem to say, and weirdly, tragically (for the alien's quarry), she's not even lying.
There are dozens of mysteries in Under the Skin that don't cohere in any logical way but work like gangbusters on the imaginative subconscious. Where, exactly, does alien Scarlett lead her victims? Who knows? But we do see them, following her lead, stripping themselves naked as they stride deeper and deeper into a pool of what looks like inky black oil. They sink, while she pads across the surface with a panther's muscular grace. What happens to them after that is the stuff of Francis Bacon paintings, a loss of self that Glazer captures with disturbingly hypnotic imagery. And Levi's score is a small, weird miracle in itself. The opening sequence, in which an orb of light is used as a kind of visual shorthand to fill us in on some otherwise incomprehensible alien back-story, is accompanied by a chorus of anxious violins like 1,000 obsessive crickets. This is the music of unease, the sound our neurons might make if we could listen in on their workday.
Alien Scarlett goes through one man after another, until one of them, a young man with a facial disfiguration (played by Adam Pearson) touches a seemingly human nerve in her. She never voices the thought, but we can see her wondering: Could she ever live as a human? Could she feel desire and make real love with a man instead of destroying him? This particular pick-up, thinking he's hit the jackpot by finding a woman who's sexually interested in him, pinches himself to make sure it's all real. "Dreaming," he says numbly as he follows in her deadly footsteps; he can barely bring himself to articulate the question mark. In her molten honey voice, alien Scarlett answers the half-asked question: "Yes. Yes, we are."
At this point, which is also, incidentally, the moment Johansson finally strips bare, Under the Skin becomes less sinister and more about some unnameable longing. Alien Scarlett seems annoyed by Earthlings at first — they're a necessary inconvenience — but the longer she wears the skin of a human, the more she yearns to become one. She doesn't have penis envy; she has soul envy. Even in her not-human state, she wants what we all want, and just like us, she has no idea how to name it. Maybe the key is to just keep walking toward it. Dreaming. Yes, we are.
