The latest in sculptor Matthew Barney’s series of (literally) art films, Cremaster 5 was shot mostly in a Budapest opera house, and it plays like an opera whose plot you can’t quite fathom—only partially because Barney’s untranslated libretto is in Hungarian. Extravagantly produced and edited with a newfound flair, the film features Barney’s customary imagery of reproduction and mating ritual: water, flowers, plumed pigeons, and egglike globes; a queen (Ursula Andress, no less), water nymphs, a near-naked giant, and a satyr. (The cremaster, of course, is the muscle that controls how closely testicles hug the body.) The 50-minute spectacle is sumptuous but baffling—it’s easy to understand why Barney’s opera house has a full orchestra but no audience. At 8 p.m. Thursday & Friday, April 16 & 17, at the Hirshhorn Museum & Sculpture Garden’s Ring Auditorium, 7th & Independence Ave. SW. Free. (202) 357-2700. (Mark Jenkins)
