Mary Stuart. To appreciate the Shotgun Players' adaptation of Schiller's 18th-century play, you must consider the set. It has two doors, three video screens, a mirror, a white board, a one-way window, and a sliding section of floor. The stage must be so involved to distract us from the fact that for nearly two hours nothing happens on it. The blocking is simple verging on primitive: Characters enter, they talk, someone leaves. That's it. The few times (you can count them on one hand) they actually touch each other are so shocking it's electric. But the electricity is real: The dialogue, semi-adapted for modern times, shines — and the actors carry a charge. Mary Stuart features superb performances, especially from Peter Ruocco (Lord Burleigh) and Scott Coopwood (Count Leicester). The compelling character conflicts and parallels with our own time make the dramatic tension in a story whose outcome we already know — how Queen Elizabeth I of England came to undo her cousin Mary Queen of Scots in 1587 — nothing short of intense. When Burleigh, speaking for the state, says, "We don't torture," the crowd just has to laugh. The conflict between morality and politics is sadly contemporary. Through Nov. 7 at Shotgun Players, 1901 Ashby (at Martin Luther King Jr.), Berkeley. $15-$28; 510-841-6500 or www.shotgunplayers.org. (Benjamin Wachs) Reviewed Oct. 27.
Shocktoberfest!! 2010: Kiss of Blood. The Thrillpeddlers are quintessential San Francisco: a bunch of freaks performing freaky shows. They emulate, celebrate, and reinterpret the Parisian shock and horror theater of the Grand Guignol with elaborate set pieces and lush, exotic costuming. Like San Francisco itself, artistic director Russell Blackwood and company aren't afraid to dabble in S&M, cross-dressing, sexual deviance, and plain old lusty fun — and this show is all of those. This round of three short plays involves severed fingers, gas masks, drag queens, botched brain surgery, and a giant functional guillotine at center stage. The Thrillpeddlers are very good at what they do, but I wish they would rely a little less on over-the-top campiness and more on what they advertise: danger, shock, and titillation. Perhaps that's why they invited the brilliant Brazilian Guignol theater company Vigor Mortis to perform with them after a few select shows (Oct. 28-31). Their one-act, The Forsaken Laboratory, is not to be missed. It's an incredibly rendered horror pantomime involving a priest, a nun, and a man giving birth to a demon. This feels like Grand Guignol's true potential. Through Nov. 19 at the Hypnodrome, 575 10th St. (at Bryant), S.F. $30-$35; 800-838-3006 or www.thrillpeddlers.com. (Nathaniel Eaton) Reviewed Oct. 27.
