Clay Dalzell (William Powell) has framed 8x10 photos of RKO actresses Irene Dunne and Ann Harding prominently displayed in his bedroom suite.
Early in the film, Clay Dalzell (William Powell) says that people consider him "Charlie Chan, Philo Vance, and The Saint all rolled into one." Powell previously played Philo Vance on five occasions, in The Canary Murder Case (1929), L'affaire Greene (1929), The Benson Murder Case (1930), Paramount on Parade (1930), and Meurtre au chenil (1933).
Ginger Rogers was very pleased with the gowns which Bernard Newman designed for this film. She particularly liked the white mink blouse with black velvet skirt that she wore in the opening scene. In her autobiography, "Ginger, My Story", she referred to it as "so Fifth Avenue". Newman also designed the costumes for eight other Rogers films: Idylle sous les toits (1933), Roberta (1935), Le Danseur du dessus (1935), Je te dresserai (1935), En suivant la flotte (1936), Sur les ailes de la danse (1936), Mariage incognito (1938), and Six destins (1942).
MGM lent William Powell to RKO for this picture immediately after his biggest box office hit, L'introuvable (1934), the first of six movies in that series. Although the combination of Powell and Ginger Rogers proved to be popular, and this film turned a tidy profit for RKO, the two stars never worked together in a film again.
A consummate worker, Ginger Rogers started working on this film within a week of finishing the filming of Roberta (1935) (with co-star Fred Astaire). Six days after this film finished shooting, she went to work on her next Astaire film, Le Danseur du dessus (1935).
