The performers are uniformly excellent. Uranowitz stands out from beginning (as mathematician Ludwig) to end (as his equally mathematical great-nephew Nathan). Krumholtz is equally adept as the conflicted family breadwinner, while Castelow impresses as the out-of-place trophy wife who models for Klimt and nearly disrupts the household. Uranowitz, Augen, and Froushan do stunning work in the play's shattering final scene. (Augen and Froushan, along with Castelow and Neil, played these roles in London.) That said, the stage is filled with too many worthy performances to individually cite.
