After a storied career in musicals on Broadway (“Rent,” “Wicked”) and worldwide acclaim as the voice of Elsa in the smash animated feature, “Frozen,” Tony Award winner Idina Menzel (pictured) has let all that go to return to live theater in Joshua Harmon’s new OffBroadway play, “Skintight” (p. 31). Why this nonsinging role now? “My singing roles have really connected me with so many people and brought me so much love,” Menzel has said. “But it is important to stretch myself as an actress, in part, because I think there is a danger of becoming pigeonholed. I know I have more to give than just a great belt!” Critics and her legions of fans agree.
