The two top-billed actors of this episode Wendell Corey and Gerald Mohr would die a day apart, respectively on November 8th and 9th, 1968, both at age 54. The leading lady here Peggie Castle would die just five years after her male co-stars in 1973 at age 45.
This episode of Zane Grey Theatre (1956) would be re-edited to air as an episode of Frontier Justice (1958) two years later under the same title, A Quiet Sunday in San Ardo (1958). But whereas Dick Powell serves as series host here, the host on the later series introducing what was otherwise the same show was Lew Ayres.
