The movie theatre featured in the film is the Marcal Theatre at 6021 Hollywood Boulevard, Hollywood, California, which featured late runs, revivals, and various odds and ends in keeping with its location on the "wrong" end of Hollywood Boulevard. The revival combination of Flight Lieutenant (1942) and Corregidor (1943) was somebody's idea of a "commemoration" of the anniversary of Pearl Harbor, the first week of December 1949, at which time "Destination: Murder" was filmed.
The $5000 that Jackie demands from Armitage is equivalent to ~$54,000 in 2020.
In this 1950 movie, a retrospective movie theater is showing Flight Lieutenant (1942) and Corregidor (1943). Posters seen outside the theater include Mr. Smith Goes to Washington (1939) and Germany Year Zero (1948).
Made independently by producer/director Edward L. Cahn. RKO bought this film from his production company two months after shooting was finished.
