Idomeneus, Sideshow Theatre Company at Storefront Theater, through Sept. 23. German author Roland Schimmelpfennig riffs on classical mythology in this modern words and movement piece about sacrifice, war, honor and vow-breaking as told by a Greek chorus of 15 in a lively hour. JA

Marvin’s Room, Circle Theatre, through Sept. 30. The comic timing might not be as fine tuned as it should be, but this laugh-filled drama involving family, disease and the ever-present threat of death is a lasting tribute to the late gay playwright Scott McPherson. SCM

Steamwerkz the Musical, Annoyance Theatre, through Oct. 5. This zany musical with plenty of gross-out humor spoofs the similarly named and notorious North Halsted gay bathhouse and (oddly enough) Alice’s Adventures in Wonderland. So “fall into the hole” while you still can. SCM

Susan Swayne and the Bewildered Bride, Babes With Blades Theatre Company at Lincoln Square, through Sept 22. The adventures of a Victorian “lady detective” include the athletic spectacle you’d expect from an all-female fight troupe, but Reina Hardy’s play also exercise our brains with its commentary on gender issues and the evil of intolerance.
