Dolores Moran the cover of such magazines as "Yank". She was given supporting roles in films, such as "Old Acquaintance" (1943) with Bette Davis. Warner Bros. attempted to increase interest in her, promoting her along with Lauren Bacall as a new screen personality when Bacall was cast alongside Humphrey Bogart in "To Have and Have Not" (1944). The film made a star of Bacall, but Moran languished, and subsequent films did little to further her career. "The Horn Blows at Midnight" (1945) gave her a leading role with Jack Benny and Alexis Smith, but her film appearances after this were sporadic, and
Lauren Bacall not provided a quick career resurgence. "The Big Sleep" laid the foundation for her status as an icon of film noir. She would be strongly associated with the genre for the rest of her career, and would often be cast as variations of the independent and sultry femme fatale character of Vivian she played in the movie. As described by film scholar Joe McElhaney, "Vivian displays an almost total command of movement and gesture. She never crawls." Bacall was cast with Bogart in two more films. In "Dark Passage" (1947), another film noir, she played an enigmatic San Francisco artist.
