"When I first became an actor, there were two young actors in New York: Marlon Brando and Steven Hill", said Landau.
Hill was born in 1922 in Seattle.
Steven Hill, best known for playing District Attorney Adam Schiff on NBC's "Law & Order", has died, his son Rabbi Yehoshua Leib Hill confirmed to CNN. Hill's character appeared in all but two episodes of the show's original 10 seasons, earning him two Primetime Emmy nominations.
His newfound observance of Shabbat, which coincides with Friday-night and Saturday-matinee performances, effectively ended Hill's stage career, according to Hollywood Reporter.
Hill's luck on television changed in 1990 with the massive success of "Law & Order", on which he played District Attorney Adam Schiff.
However, he was still able to work in television. He later told The New York Times that the legalese used on "Law & Order" made it "like acting in a second language".
In addition to being one of the founders of The Actors Studio, he was also one of the original characters in the '60s show Mission: Impossible.
"Steven has more moral authority than anyone else on episodic TV", Wolf said.
Already an accomplished entertainer at the time, Hill scored the enviable role of Daniel Briggs - the leader of a top-flight secret agency unit - on the popular "Mission: Impossible" show in 1966. Other notable films over the years included "Teachers", "Brighton Beach Memoirs" and "Legal Eagles".
Hill is survived by four children from his first marriage and five children with his current wife, Rachel.
