Talkin' 'bout a revolution: Margaret Cho's new comedy concert film, Revolution, debuts on Sundance Channel--and she's as pissed off and hilarious as ever.

Margaret Cho once categorized herself as "not straight, not gay, just slutty. Where's my parade?"

With her latest film, Revolution, set to premiere on Sundance Channel in June as part of the month-long "Out Loud" celebration of Gay Pride Month, she takes the opportunity to update her description of her sexual identity.

"I'm a queer," Cho says. "I'm married to a man and somewhat ashamedly heterosexual. I've had relationships with women and men, and I have fallen in love with a man, and it's a marriage that's important to me. It also makes sense that I'm a gay man. I'm also transgendered. I believe that I am all of these things. These identities all apply to me. I want to come out as everything, because I am." She takes a breath. "It's something I've always dealt with."

What that means now--onstage and off--is that Cho, 35, has to work harder for gay rights. She says all this on the phone from a Dallas hotel room, where she's test-running yet another new concert piece, A Stale of Emergency, which she'll tour in time for the presidential election this fall. Marriage rights for everyone in this country--and the world, certainly, because Cho thinks big--have become her focus. "That's where I see inequality," she says. "That's where I see injustice. To me, gender is very fluid. Justice is not. Justice is not negotiable."

In Revolution, shot at Los Angeles's Wiltern Theatre, Cho enters the stage in full geisha gear (save for high-heeled Roberto Cavalli boots), but, somewhat metaphorically, she can't keep the act up long. She sheds her wig, her tiara, those boots--that Asian identity--no less than 15 minutes into the show, saying, in effect, that she's not just Korean American. While other queer comics are still making funny observations about life outside of the bedroom to keep their TV shows sanitized, perhaps it's this sartorial freedom that allows Cho to explore some of her most achingly personal, provocative, and political material to date. There's very little aping of her mother here. In one skit a woman's nether regions explode and are sewn back together. Also, she calls out those who would dare deny anyone the right to marry.

"I've never seen American polities go so wrong," Cho says. "Gay marriage evolved into Janet Jackson and then the [Donald] Rumsfeld hearings on Iraqi prisoner abuse. We should not forget that we are still fighting this cultural war."

Her defiant courage and clarity of vision may come from a very traditional place: her year-old marriage to Alan Ridenour, who helped her understand what family means. "There's nothing like wedded bliss," she purrs. "There's nothing like it. I understand what it means to love somebody and, therefore, understand what it means to have a family. Regardless of who I'm married to, those family values will stick with me. I've always been queer. My values come from within the queer community."
