I loved his performance in that play, which unfortunately was his only Broadway appearance
He was also, briefly, announced to appear in STRAIGHT WHITE MEN (replacing Tom Skerritt who had to bow out), but he never played a performance.

Sad news. I saw both Off-Broadway and Broadway productions of Heisenberg and thought it was a remarkable piece. He had such an easy, natural chemistry with Mary-Louise Parker, and he imbued that character with such kindness and gentleness. I’m glad I had the chance to see him.
