A Hollywood Reporter production chart places Erford Gage in the cast, but his participation in the completed film has not been confirmed. The Variety review incorrectly identifies this film as Mexican Spitfire's Baby, the title of a 1941 "Mexican Spitfire" film. This was the eighth and final film in the series. The Hollywood Reporter review and a news item in Hollywood Reporter note that the studio announced its intentions to produce a new series based on the "Lord Epping" character, but that series was never made. In Hollywood Reporter news items, the "Mexican Spitfire" series was occasionally referred to as the "Lord Epping" series. For additional information about the series, consult the Series Index and see the entry for Mexican Spitfire in AFI Catalog of Feature Films, 1931-40; F3.2846. This film marks the last screen appearance for Lupe Velez, who commited suicide on December 14, 1944. Two films were made about her in the 1960s: a 1966 Andy Warhol picture titled Lupe, starring Edie Sedgwick, and a 1967 Film-Makers' Cooperative film, also called Lupe, starring Maria Montez (see AFI Catalog of Feature Films, 1961-70).
