In 1953, Cornell found a suitable role in "The Prescott Proposals", about a United States Delegate to the United Nations. Christopher Fry wrote a verse drama "The Dark is Light Enough", set 1848 Austria. The cast included Tyrone Power, who played the love interest, Lorne Greene, and Marian Winters. (Christopher Plummer was Power's understudy. In his memoir, Plummer states that Cornell was "the last of the great actress-managers," and that she was his "sponsor.") In 1957, Cornell staged "There Shall Be No Night", the Pulitzer Prize winning play by Robert E. Sherwood, adapted to the events of the Hungarian Revolution of 1956. This play was adapted for TV and broadcast on NBC's Hallmark Hall of Fame with Charles Boyer, Bradford Dillman and Ray Walston. Another play by Fry, "The Firstborn", was set in Biblical Egypt, with Anthony Quayle playing Moses. Leonard Bernstein, recently appointed musical director of the New York Philharmonic, wrote two songs for the production. The play toured in Tel Aviv in 1958. She continued with several other forgettable plays, and her last production was "Dear Liar" by Jerome Kilty.
