With the coming of World War II, a new type of Hollywood actress appeared on the big screen.
California historian Kevin Starr described it thus:
The stars emerging in 1940, by contrast—Rita Hayworth, Ann Sheridan, Ida Lupino, Lupe Vélez, Marie Windsor, Lana Turner, Lizabeth Scott—each possessed a certain hardness, an invisible shield of attitude and defense, that suggested that times were getting serious and that comedy would not be able to handle all the issues... Just a few years earlier, Hollywood had been presenting the wisecracking platinum blonde, frank, sexy, self-actualizing.
Now with the war, that insouciance had become hard-boiled.

This "hard-boiled" quality appeared in Scott's two previous films and was repeated in Desert Fury (1947), the second noir filmed in color and a Western as well.

In December 1946, Scott again starred with Lancaster, Corey, and Douglas, in Wallis's I Walk Alone (1948), a noirish story of betrayal and vengeance.

More drama occurred behind the scenes of the film, originally titled Deadlock.
The Kay Lawrence role was originally intended to be Kristine Miller's breakout role, but Scott, ever competitive with all other actresses, grabbed the role for herself.
Miller later recalled, "(Wallis) planned to star me in 'I Walk Alone.'
He tested me with Burt; it was a wonderful test, but then Lizabeth Scott decided she wanted the role, and Lizabeth got whatever she wanted—from Hal Wallis! (
Laughs) So, I got the second part instead."
Douglas, while working with Lancaster on the film, noted:
Lizabeth Scott played the girl we were involved with in the movie.
In real life, she was involved with Hal Wallis.
This was a problem.
Very often, she'd be in his office for a long time, emerge teary-eyed, and be difficult to work with for the rest of the day.

Though relations between Lancaster and Scott had previously been romantic, a falling out happened.
Lancaster's behavior toward Scott was chilly, especially during one kissing scene, leaving Scott looking exasperated.
By April 9, 1947, Lancaster tried to break his seven-year contract with Paramount.
He claimed it violated a previous freelance deal, but added that he did not want to work with Scott anymore.
Despite all the issues among the cast and past critics, I Walk Alone is usually now judged to be a film noir classic.

In January 1948, the 26-year-old Scott played her third and last ingénue in the second favorite among her own films—Pitfall (1948) with Dick Powell and Jane Wyatt as a middle-aged couple growing apart.
Director André de Toth explained his reasons for casting Mona:
I wanted Lizabeth Scott.
I didn't want some blonde with big tits.
You had to believe that this girl was real.
Even if I took one of these over-sexed types who could not act, it would change how the Powell character is drawn into the affair.
Remember the point of the script was that he's just a middle-level insurance investigator.
He's tired of his job, spending time in his little office with a drab secretary.
So I could have made a different picture, with a prettier girl than Lizabeth Scott, and told the story of that girl, her problems, but that wasn't this movie.
That would make it phony, if you cast it with Marilyn Monroe, a type like that.
I needed somebody real.

In May 1948, it was announced that Jane Greer and Robert Mitchum would star in a football-themed story by Irwin Shaw, originally titled Interference.
Afterward, Lucille Ball replaced Greer and Victor Mature replaced Mitchum.
Scott was slated to play the club secretary.
Then, she replaced Ball as leading lady.
The reason for the role switch is unknown, though Ball never forgave Mature for his rudeness when they made Seven Days' Leave (1942).
The 37-year-old Ball was in career slump at the time and had to take the secondary role meant for Scott.
The final film, titled Easy Living (1949), received a generally negative response when it was released.
The New York Times review was uncommonly positive, though dismissive of Scott's performance.

In September 1948, Scott played the ultimate femme fatale in Too Late for Tears,
