The film was fairly closely based on the real-life murder of New York showgirl Dorothy "Dot" King in March 1923. Like the character of Miriam King in the movie, the real Dot King was both a perpetrator and a victim of blackmail, and was having simultaneous affairs with at least two rich married men. Other films inspired by the Dot King murder include La Canarina Assassinata (1929) and La città nuda (1948).
This film's earliest documented telecast took place in Los Angeles Tuesday 5 September 1950 on KLAC (Channel 13).
