A veteran of Boston’s theater scene, Steinbach exhibits astonishing versatility—and this year was one of her best yet. As a founding member of the Actors’ Shakespeare Project, she played not one but two ancient kings: Nestor and Priam, in Troilus and Cressida. Then, when the Boston Playwrights’ Theatre staged Deported, a dream play, Steinbach excelled as an Armenian-genocide survivor. But her biggest triumph was in the New Repertory Theatre’s Collected Stories by Donald Margulies. That performance as an aging author betrayed by her protégé won her the Independent Reviewers of New England’s best actress award.
