Veronica Lake and Fredric March did not like one another, due in part to some disparaging remarks March made about her. During filming, Lake delighted in playing pranks on March. In one scene in which the two were photographed from only the waist up, Lake stuck her foot in March's groin. In another incident, Lake hid a 40-pound weight under her costume when March had to carry her in his arms. After that incident, March nicknamed the film "I Married a Bitch".
Sol Saks, creator of Bewitched (1964), stated in an interview for Bewitched (1999) that he drew inspiration both from this film and Bell Book and Candle (1958) in creating the iconic TV series. Columbia Pictures owned the rights to both of those movies. Since it also owned the television studio that was to produce "Bewitched," Saks didn't worry about getting sued.
Dalton Trumbo was a contributing writer, but left because his interpretation of the novel differed from that of producer Preston Sturges. Sturges also left the production (and declined onscreen credit) because of artistic differences with director René Clair.
Actress Leslie Caron was very close to René Clair. In her 2009 autobiography, she says the director spoke 'with affection' about Veronica Lake: "The trouble with her is she didn't have confidence in herself. Nothing could convince her that she was beautiful. It was a fight every morning to get her to face the camera".
Charles Chaplin was a fan of director René Clair. After seeing this film he told Clair, "There was no need to see the credits, in two minutes I had known it was your work."
