Sept. 26-Nov. 11: Robert O’Hara plays a theater game here with what works out to be a big payoff. In this San Francisco Playhouse production, O’Hara presents an intervention at a family barbecue, first with a white family playing out their dysfunctional relationships, and then a black family in the same setting and situation.

O’Hara, a gay, black playwright, is always good at upending our prejudices and preconceptions about family and race, and this structure should give him lots of room to make audiences squirm. Bay Area theater veteran Margo Hall does a terrific job playing a role and directing the dual casts, It’s funny and touching, and very real. Details here.
