Theater is where you find it this fall. For instance, at a warehouse party where assembled guests artists, authors, bons vivants, goatees, and rockers of all stripes get so carried away that a play suddenly breaks out among them (it can happen). Or in the offices and cubbyholes where a group of Dutch actors retreat midperformance to mine universal truths about the minutiae of mundane alienation. Or hovering just above the stage, where astrocosmonautical new best friends, stranded like circus performers, orbit together after a space shuttle disaster. Or on a kitschy converted kid shuttler known as the Mexican Bus, which a trio of disembodied Chicanos use to cruise the Mission. Theater, in short, is going to be a ubiquitous presence, maybe even the stranger eyeing your canapé, so watch out.

San Francisco Fringe Festival It's the 16th annual array of 50-minute feats, under-an-hour undertakings, and terse tirades. Perennially fast, cheap, and out of control.

Expedition 6 San Francisco hosts the world premiere of playwright-director (and well-known actor) Bill Pullman's theatrically stylized, documentary-based take on the real-life encounter between Russian cosmonauts and American astronauts stranded in space after the 2003 Columbia shuttle disaster. Think of it as Apollo 13 with a trapeze.

The MagiCCal Mission Tour Albeit now in Los Angeles, the performers of Culture Clash (Richard Montoya, Ric Salinas, Herbert Siguenza) are forever local theater champs with deep roots in the Mission District. In a unique take on the guided tour, they climb (virtually) aboard the rolling fiesta known as the Mexican Bus to act as your (prerecorded) guides through their own private Mexico (del Norte).

Kommer This Yerba Buena Center for the Arts engagement marks the Bay Area debut for Kassys, the acclaimed Amsterdam-based Dutch theater company. A physically exact multimedia work, Kommer (Dutch for "sorrow") begins as a comical and poignant play about a group of friends gathered in mourning, then shifts gears to follow the individual actors out of the theater as each returns to a separate little workaday world, shedding light on "private and public moments of human frailty."

Continuous City This work in progress exploring postmodern interconnectivity and our changing sense of place in a global context is a tech-savvy performance piece that attempts to extend the reach of theater by, among other things, uploading video contributions from a social networking site. It's a collaboration between Bay Area actors, UC Berkeley students, and New York's the Builders Association (responsible for the visually stunning Super Vision at the YBCA in August 2006).

Des Moines Campo Santo premieres Denis Johnson's fast-paced, darkly poetic, hilarious, and fascinating multicharacter stream of confession and moral conflict. The brilliant author turned playwright's past collaborations with the company include Psychos Never Dream and Soul of a Whore. In what Intersection for the Arts and Campo Santo are calling their take on dinner theater, the play will unfold amid a hip cocktail mixer in a warehouse not far from the company's usual digs on Valencia.

Slouching Towards Disneyland Inimitable radio and stage personality Ian Shoales (a.k.a. Merle Kessler) and quick-fingered, ever-versatile musician-composer Joshua Raoul Brody team up for this wry, cranky song and rant, purportedly "a wild ride in words and music through world history from Genesis to George W."
