Thrill Crazy… Kill Crazy… Gun Crazy -A tagline for the film
Since he was a little boy, Bart Tare (John Dall) has loved guns. After 4 yrs. of reform school, then a stint in the Army, he returns home to his small town. His older sister (Ruby)- who raised him after they lost their parents- is now married w/ 2 young kids. His two best friends (a cop named Clyde and a newsman named Dave) take him to a carnival; he meets Annie Laurie Starr, a blonde/petite woman who is a sharp-shooter. Laurie loves guns as much as Bart- even getting him a job! They end up getting married, leaving the carnival (after the boss hits on Laurie), and have a long honeymoon where they live it up. When they get low on money, Laurie tells Bart her idea- robbery!
I told John, “Your c*ck’s never been so hard,” and I told Peggy, “You’re a female dog in heat, and you want him. But don’t let him have it in a hurry. Keep him waiting.” That’s exactly how I talked to them and I turned them loose. I didn’t have to give them more directions. -Joseph H. Lewis, director
This film is based on a story written by McKinley Kantor reworked by Dalton Trumbo (who was blacklisted). Here we see the linking of sex and violence; it also reveals that guns are a big part of American life. Though this was an inexpensive B movie, it has some fine elements that were ahead of its time. Director Joseph H. Lewis uses long takes, angles, deep focus, and jerking camera movements. Lewis also gave the actors permission to improvise. As the hosts commented on Out of the Podcast, “Bart and Laurie are equals” and “are the only ones who understand each other.” Though Bart avoids shooting anyone, Laurie isn’t as careful; she tells him early on that she’s “no good” and wants some “action” (excitement). Dall and Cummins have great chemistry; they are like two magnets instantly drawn to each other. Coming from the theater, Dall is also not afraid to express emotions (incl. fear and doubt).
Dall and Cummins did all their own driving in the film; only one process shot (i.e., rear projection behind the actors pretending to drive) was used in the film. The cinematography by Russell Harlan is a standout. The bank heist sequence was done in one take, with no one outside the principal actors and people inside the bank aware that a movie was being filmed. When Bart says, “I hope we find a parking space,” he really meant it. At the end of the scene, someone screams that there’s been a bank robbery; this was a bystander who saw the filming and assumed the worst.
 It’s psychological side of danger, pathological lies, and the pattern of a downward spiral in having to commit violent acts (even un-intentionally), becomes what really pulls in the viewer into the picture, aside from the more loose, on-location ‘real’ style and interesting camera-work.
 Peggy Cummins is really good in this. …her baby-doll voice creates an effective contrast to her colder-than-ice attitude. She’s crooning into her lover’s ear one minute and itching to kill someone the next.
I thought John Dall was at first odd casting for the role of Bart. Annie is supposed to think of him as a man’s man, and Dall, with his willowy physique and gentle mannerisms is far from that. But then when we realize that he’s at heart really too gentle for the life he and Annie have chosen for themselves, his casting makes sense.
 What is the quintessence of a film-noir? A good answer is: an evil strong woman that manipulates a weak, although basically decent, man, involving him in a crazy love, doomed to a tragic ending. Then we can safely state that “Deadly is the Female” [the original title] is a perfect instance of film-noir.
The movie has outstanding merits. The cinematography, and especially the camera-work are excellent, and comparable to the best achievements in the film-noir genre.
