Jane Randolph was wanted for the role of Pat Cameron. However, she turned it down, as she was upset at being uncredited in Anthony Mann's previous picture, T-Men (1947). Claire Trevor eventually was cast.
Part of the reason this film looks so authentic is the costumes. Rick's dressing gown is a silk Sulka, the most expensive made for almost a hundred years, and he smokes with a solid gold Cartier holder that would fetch $2-3k today.
In Harlan Ellison's post-apocalyptic novella on which A Boy and His Dog (1975) is based, the main character goes to one of the few surviving movie theaters and watches Raw Deal (1948). He lives in a world dominated by gangs and describes the movie: "Gangsters, mobs, a lot of punching and fighting. Real good."
The $50,000 Joe wants from Rick would equal nearly $615,000 in 2022.
Ann's car is a 1946 Dodge Custom convertible coupe. New, it cost $1,649 (over $25,000 in 2022). In excellent condition, it can fetch over $50,000 at auction. Practically unchanged from the 1946 through 1949 model years, only 9,500 were made.
