Jonathan Glazer makes ambitious, scary movies, but he's not prolific — his last outing was "Birth" (2004), a film starring Nicole Kidman that gave new meaning to the word "creepy." Now he has made "Under the Skin," an elegant but queasy piece of cinematic poetry which recalls "2001: A Space Odyssey." Stanley Kubrick explored the relationship between man and machine, proffering insights on what it is to be human in a digital world. Inspired by a novel by Michel Faber, Glazer looks at the human condition through the body, or more specifically, our skin.
