Jeanne Crain Alan Young, and Rudy Vallee. The production was filmed on location in Paris. The film was based on Anita Loos' novel, a sequel to "Gentlemen Prefer Blondes". "Gentlemen Marry Brunettes" was popular throughout Europe at the time and was released in France as "A Paris Pour les Quatre" ("To Paris for the Four"), and in Belgium as "Cevieren Te Parijs". Later in the 1950s, Crain, Russell, and another actress formed a short-lived singing and dancing lounge act on the Las Vegas Strip. Crain made the Western comedy "The Second Greatest Sex" (1956), then starred with Glenn Ford, Russ Tamblyn, and
The Age of Adaline 5. On March 11, 2014 filming at the Hotel Vancouver commenced. Anamorphic lenses and minimal use of steadicams were employed to provide greater authenticity for scenes set in the 1930s, 1940s, and 1950s. The films "Gentlemen Prefer Blondes" and "How to Marry a Millionaire" served as inspiration for the period color tone and saturation. While Rob Simonsen scored the film, Lana Del Rey contributed a song titled "Life Is Beautiful". The song is featured in the film's trailer but is not included in the soundtrack. On August 15, 2014, Lionsgate set the film for a January 23, 2015 worldwide release.
