Gray worked steadily in the 1950s, but mostly in smaller movies. She played a crooked nurse in "The Sleeping City" (1950) and appeared in "Kansas City Confidential" (1952) and in the Stanley Kubrick film noir "The Killing" (1956), in which she played a lonely woman desperate for love. In the 1953 Western "The Vanquished", she played a woman who attacks Jan Sterling's character with a pair of scissors in a crazed attempt to exonerate the man she loves (John Payne). Other films included "Father Is a Bachelor" (1950), "The Leech Woman" (1960), "The Phantom Planet" (1961), and "P.J." (1968).
