Art: Henri Cartier-Bresson and Exposed Exhibits
If you've never heard of Henri Cartier-Bresson, stop reading and hit the books fast. Considered by many to be the father of modern photojournalism—he adopted the 35 mm format very early on—Cartier-Bresson set the stage for a style of candid photography that came to be known as real life reportage. This major retrospective spans the artist's entire career and is one of the biggest shows to hit SFMOMA this year. While you're there, check out Exposed, a look at how the camera transformed the idea of voyeurism. $18; Saturday 10/30 - 1/30/2011; SFMOMA, 151 Third St., sfmoma.org

Film: Dr. Jekyll and Mr. Hyde
Chances are you'll be burnt out from all the pre-Halloween partying on Saturday night to muster up more strength for the actual day. Celebrate the holiday instead with a high-brow, low-key combo. Davies Symphony Hall will play the newly restored 1920 silent classic film Dr. Jekyll and Mr. Hyde with live musical accompaniment by the Ruffatti Organ. See John Barrymore bring Robert Louis Stevenson's creepy character to life. Buster Keaton's shortThe Haunted House will open. $20-$65; Sunday 10/31; Davies Symphony Hall; 301 Van Ness Ave., sfsymphony.org

Dance: Hubbard Street Dance Chicago
From humble beginnings to international prominence, Hubbard Street Dance Chicago is a company to be watched whenever they come through town. The L.A. Times says, “This is the kind of dancing one always hopes to see,” and the Chicago Sun-Times calls their performances “consistently hypnotic.” The 17-member troupe, led by artistic director Glenn Edgerton, will perform four West Coast premieres, including Nacho Duato’s Arcangelo (the only US company to ever perform this work), Deep Down Dos, Blanco, and 27'52" by Czech choreographer Jirí Kylián. $32-$68; Friday 10/29 - Saturday 10/30; Zellerbach Hall, Telegraph Ave. and Bancroft Way, Berkeley, calperfs.berkeley.edu

Performance: We Are All Together, Alone in the Wilderness
Here's something new and exciting on the performance front: a one-time-only presentation by Stijn Schiffeleers and Michael Swaine that chronicles the life and work of naturalist Richard Louis Proenneke during his 30 years of solitude in the mountains of Alaska via an original multi-media platform. We Are All Alone, Together in the Wilderness features performances on a musical sewing machine (i.e. foot-powered finger piano), Beat Blocks (a wooden interface for a rhythm sequencer), a tree stump record player, a canoe, buckets, a two-person saw, and a screening of the re-edited Alone in the Wilderness footage of Proenneke's daily explorations. Free; Friday 10/29; Southern Exposure, 3030 20th St., soex.org
