Projectile blood is just one spectacle in Shakespeare’s problem play, Troilus and Cressida, as staged at Central Park’s Delacorte Theater, a fine Public Theater production directed by Daniel Sullivan. Written around the same time the bard penned his most famous tragedy Hamlet in 1602, T&C features warriors waging battle in the Trojan War, and as in Hamlet, the play asks the question, what makes a man? In Hamlet, after the hero’s death, Fortinbras, loosely translated as a French “strong in arms,” takes over. Might makes right, right? The more obscure T&C’s message is more muddled: Strong arms do not necessarily make for good men. The high body count is not worth the loss. And love, as in the kind young Troilus has for Cressida, does not elevate. In modern dress, and performed by an exceptional cast, including John Glover, Corey Stoll, John Douglas Thompson, Max Casella for his comic relief, and with a hunky Bill Heck as Hector and Andrew Burnap as his younger brother Troilus, this male ensemble shows men doing what men do.
