Cirque du Soleil movies are a lot like ballet films — long on beauty and artistry, short on story.

“Cirque du Soleil: Worlds Away” is a 3-D catalog of the wonders of the Cirque company’s Las Vegas shows, from “Believe” and “Mystere” to “O” and “Viva Elvis.” It is a feast for the eyes, an appreciation of the accomplished art of the jugglers, mimes, acrobats and aerialists.

Live and in person, these shows are physical and technical spectacles, the state-of-the-art in what is possible in live performance. On film? The spectacle is a little less spectacular, the sappy Enye-ish score monotonous and the “story” takes on importance that it cannot sustain.

Their movies are what the live shows never are — boring. It’s all quite lovely, mesmerizing — and right on the edge of sleep-inducing.

Then, just as you’re about to doze off, the “Viva Elvis” and “The Beatles Love” segments give the show momentum and a beat we can dance to.

Cheaper than a trip to Vegas, “Worlds Away” is, even in gorgeous 3-D, a reminder of the indispensable place Cirque du Soleil holds in popular entertainment. There’s no substitute for live performance.
