When Willie Comes Marching Home is a 1950 World War II comedy film directed by John Ford and starring Dan Dailey and Corinne Calvet. It is based on the 1945 short story "When Leo Comes Marching Home" by Sy Gomberg. The film won the Golden Leopard at the Locarno International Film Festival.

Corinne Calvet, born Corinne Dibos, was a French actress who appeared mostly in American films. According to one obituary, she was promoted "as a combination of Dietrich and Rita Hayworth", but her persona failed to live up to this description, though the fault lay as much with a string of mediocre films as with a lack of a compelling talent, for Calvet's sultry looks and flashing eyes were allied with an impish sense of humor. She eventually became better known for her fiery private life and some well-publicized legal battles.
