Saturday Happenings

Movies

It is hot, muggy, and miserable. Perfect movie weather. And the Brattle will help you spend the entire day in its air conditioning by showing every movie in "The Thin Man" series, a trick the theater first pulled 20 years ago. As Dashiell Hammett's detective couple Nick and Nora Charles, William Powell and Myrna Loy had one of the best ongoing on-screen romances of the 30s and 40s. The movies are witty and cynical and never too hardboiled to crack a joke. Brattle Theatre, 40 Brattle St., Cambridge. More information.

It's Brando mania at the HFA, as the Archive continues its Elia Kazan retrospective. Viva Zapata! (1952) is the rare chance to see Brando, the Mexican revolutionary, with a mouthful of John Steinbeck's words. A Streetcar Named Desire (1951) is the one where the method actor says "Stella." Harvard Film Archive, Carpenter Center, 24 Quincy St., Cambridge. More information.

Water Wars

We mentioned the Banditos Misteriosos' Revolutionary War Gun Battle yesterday, but if you haven't signed up by now, it may be too late to enlist in the war. If you're left out of the wacky, wacky wet fun and feel lonely, hoof it over to Allston for the second annual Allston Squirt Gun Day. The likelihood of police altercations is much higher at the latter event, if that's your thing. Banditos; Allston Squirt Gun Day.

Dancing Gay Hipsters

The new JP gay dance night "This is Why They Hate Us" promises to "make the Alchemist EXPLODE" with "H1GAY1 Dance Virus." Alchemist Lounge, 435 S. Huntington Ave., Jamaica Plain, 10 p.m. Free.
