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.
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".
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.
Apparently, Fredric March was no more popular with the crew than he was with Veronica Lake, as the crew helped her with the prank involving hiding a 40-pound weight under her skirt when March had to carry her in a scene.
Joel McCrea was initially cast as the lead but declined the role, because he didn't want to work again with Veronica Lake, his co-star in Sullivan's Travels (1941).
