Mexican Spitfire at Sea is a 1942 American comedy film directed by Leslie Goodwins and written by Charles E. Roberts and Jerry Cady.

The film stars Lupe Vélez, Leon Errol, Charles "Buddy" Rogers, ZaSu Pitts, Elisabeth Risdon, and Florence Bates.

[1][2][3] Carmelita Lindsay (Lupe Vélez) believes she's finally going away on a honeymoon, which she has been unable to arrange due to her husband Dennis's constant business deals.

Dennis (Charles "Buddy" Rogers) secretly intends to use this ocean voyage to sell advertising to the well-to-do Baldwins (Florence Bates and Harry Holman), with help from his Uncle Matt and Aunt Della (Leon Errol and Elisabeth Risdon).

On the cruise, a quarrel with Carmelita results in Dennis being thrown out of his cabin and into another occupied by Parisian blonde Fifi Russell (Marion Martin).
