Mexican Spitfire refers to a series of eight comedy films released by RKO Pictures between 1940 and 1943 starring Lupe Vélez and Leon Errol.
The movies featured the character of Carmelita Fuentes (Lupe Vélez), a sympathetic but temperamental Mexican singer who leaves her career and native country to meet and marry Dennis Lindsay (Donald Woods in the first three, Charles "Buddy" Rogers in the next three, and Walter Reed in the final two), an elegant and handsome American advertising executive.
The premise is based mainly on the culture shock facing Carmelita in her new married life, especially when she gets to know the family and friends of her husband, including his stuffy Aunt Della (Elizabeth Risdon).
In the earliest entries, the Lindsays are engaged or newly wed, and Aunt Della strongly disapproves of her son's choice; she schemes to reunite Dennis with his former flame, the catty Elizabeth Price (Linda Hayes).
At the end of the third film, Mexican Spitfire Out West, hotel house detective Grant Withers shows Leon Errol a moose head and asks, "What should I do with this?"
