At the start, we hear him say, “Some people wonder why I can’t stand still while I’m singing; I’ve tried it and I can’t do it.” That’s a good description of Luhrmann’s filmmaking, too, which zings and pings and never stops moving, making director and subject a great match. As Elvis sings, we see performances from several concerts, sometimes from different eras, seamlessly stitched together, so we’re not just enjoying the music but also getting a kind of panoramic view of his career. Occasionally a snippet of biographical detail surfaces, always with a clip from an interview or sometimes a darker hint. (A montage of Col. Tom Parker, his controlling manager, plays while Elvis sings “You’re the Devil in Disguise.”) There are plenty of familiar tunes, and some playful bits, too. At one point he rolls back and forth between “Little Sister” and The Beatles’ “Get Back,” to the delight of the audience.
