The films she appeared in included Shock Treatment and Caged. In 1948, Director Cecil B. DeMille cast her as Miriam, the Danite girl who loves Samson, in his film Samson and Delilah. In his autobiography, DeMille wrote that Deering was "one whose talent and dedication to her art should carry her very far in the theater, whether on screen or stage." DeMille cast her again, this time in the role of the real biblical Miriam, the sister of Moses, in The Ten Commandments (1956).
