 Sally's paranoia becomes the dominant theme of the last half of the film.In this regard, film scholar Mary Ann Doane points out, "The Two Mrs. Carrolls" is one of many "paranoid women's films" which were common in the 1940s.These include "Caught" (1949), "Dragonwyck" (1946), "Experiment Perilous" (1944), "Gaslight" (1944), "Jane Eyre" (1943), "The Locket" (1946), "Secret Beyond the Door" (1948), and "The Spiral Staircase" (1946).
