The Cow and I is purportedly based on the wartime experiences of its star, French farceur
Fernandel. The horse-faced comedian plays a French farmer stuck in Germany strong-armed into working for the Nazis. Deciding to escape, Fernandel and his faithful cow walk across Deutschland to his home in France. After a series of picaresque adventures, the farmer and his bovine buddy make it to French soil, only to run afoul of collaborators. The Cow and I was originally released as La Vache et le Prisonnier. ~ Hal Erickson, All Movie Guide
