Rainer Werner Fassbinder's dark 1968 play, about the clash between a group of small-minded German laborers and a Greek "guest worker," is a good choice for the Side Project: its small space echoes Fassbinder's claustrophobic worldview. And director Jesse Weaver's motley cast of energetic haters conveys the same nasty, brutish quality as Fassbinder's own ensemble, who also appeared in the low-budget 1969 film version. Faela Stafford is especially strong in the role originated by Hanna Schygulla. There's more honest, soul-stirring drama in this 40-minute play than in many three-hour productions. --Jack Helbig a Through 4/1: Sun-Wed 7:30 PM, Side Project Theatre, 1439 W.
