William Smith was probably best known for his portrayal as "Falconetti" in Rich Man, Poor Man (1976). He first came to the screen as a child actor in films such as Going My Way (1944) and The Song of Bernadette (1943), before entering the service during the Korean War, where his fluency in foreign languages landed him in the N.S.A. Security Squadron 6907. While working towards his doctorate, he landed a contract with MGM and never looked back. Over the next thirty years, Smith became one of the kings of B-movie and television villainy. Smith died in Woodland Hills, Los Angeles in 2021, aged 88.
