In a hushed and empty Broadway theater, two men appear onstage in street clothes, each wielding fearsome-looking broad swords. One lunges at the other, who quickly strikes back. They exchange a flurry of slices and counter-slices, with the screech of metal on metal.
Watching it with a smile is B.H. Barry, the legendary fight director who is choreographing this clash for a lush new revival of “Camelot” at Lincoln Center Theatre. An hour before every show, he leads the actors through their movements, like a conductor with an orchestra of lethal instruments.
