Was "Mary Moore" in the Suspense episode Bon Voyage the later very famous Mary Tyler Moore?
No. It was a Mary Alice Moore who was working in New York, especially in some soaps operas on radio (and probably TV). She is listed at IMDb and was in many NY television productions in the 1950s. https://www.imdb.com/name/nm0601590/ In 1973, she married Broderick Crawford, and newspapers reported her name as "Mary Alice Michelle Moore." Together, they toured the country in regional theaters in various plays during the 1970s and 1980s.
