Kilty, whose work was known to Broadway audiences and around the world, was driving north on Hillside Road when his vehicle collided with a vehicle driven by Balvin Petgrave from Bridgeport, who was driving north on Georgetown Road. Petgrave was critically injured.
Kilty drove into the path of Petgrave’s car, and he died of cardiac arrest at Norwalk Hospital, Weston Police Sgt. Patrick Daubert said.
He is known for his acting appearances on Broadway and his original play "Dear Liar: A Comedy of Letters," which he directed on Broadway in 1960. Kilty also co-founded the Brattle Theater Company in 1948 and appeared on early television shows such as "Kraft Television Theatre," "Studio One" and the "United States Steel Hour."
