all day: Movies

If “Eyes Wide Shut” made you wonder about the fuss over Stanley Kubrick, check out two of his best-regarded films, “A Clockwork Orange” and “Full Metal Jacket,” at the New Beverly Cinema. “A Clockwork Orange” (1971), Kubrick’s scintillating fable about evil, tyranny and free will, stars Malcolm McDowell as Alex, a sadistic anti-hero who undergoes “violence aversion therapy.” “Full Metal Jacket” (1987) is Kubrick’s weirdly austere look at the Vietnam War. Both films explore the dehumanizing effect of violence on the collective and individual psyches; it’s a challenging double feature but wholly satisfying for the serious moviegoer.

* Stanley Kubrick double feature, New Beverly Cinema, 7165 Beverly Blvd., L.A. Sunday: “A Clockwork Orange,” 2:40 and 7:30 p.m.; “Full Metal Jacket,” 5:15 and 10:05 p.m. Monday-Wednesday: “A Clockwork Orange,” 7:30 p.m.; “Full Metal Jacket,” 10:05 p.m. $3 to $6. (323) 938-4038.

8 pm: Cabaret

Arnold Schoenberg and Elvis Presley meet in the personality of Elvis Schoenberg, the irreverent leader of Orchestre Surreal. This strange and wacky 19-piece orchestra, with its wiggy vocalist Miss Thing, brings odd twists to rock ‘n’ roll classics, inserting bits of Ravel’s “Bolero” in the Rolling Stones’ “Satisfaction” or referencing the theme from “The Andy Griffith Show” while covering Creedence Clearwater Revival. Somewhere, Spike Jones is smiling.

* Elvis Schoenberg’s Orchestre Surreal, Cinegrill, Hollywood Roosevelt Hotel, 7000 Hollywood Blvd., Hollywood, 8 p.m.. $10. (323) 466-7000.

5 pm: Theater
