Released on April 24, 1965, it was directed by Robert McKimson and produced by the award winning DePatie-Freleng, the production house responsible for the Pink Panther and other series of cartoons released by MGM.
Mel Blanc voiced Daffy Duck, Speedy Gonzales, and the mice.
Its run time is six minutes, the standard length of a Warner Brothers cartoon since pre-48 days. It was released in the U.S.A. in English.
This cartoon is a semi-remake of Friz Freleng's "Bunker Hill Bunny". It has Daffy and Speedy fighting with cannons.
A group of starving mice are admiring Daffy Duck's Mexican plantation (aptly named El Rancho Rio Daffy), all the while wishing to have some of his home grown food. Evil land baron, Daffy, who isn't particularly fond of beggars, suddenly appears and angrily whips the mice for "starving on his property." Unfortunately, Speedy Gonzales interrupts and startles Daffy, at which the little black duck declares war on the mouse. The two proceed to do battle in private forts, resorting to everything from cannonfire to mine fields. At the end, Speedy (exhausted from doing battle with Daffy) quits and goes home. Daffy then declares victory and rewards himself with a 21 gun salute. Unfortunately, as he pulls the strings to fire his rifles, the rifles flip in his direction and blast him one-by-one (with Speedy observantly keeping count).
On CBS, the part where Daffy cracks his whip at a peasant mouse and the peasant mouse's sombrero splits in two (similar to a gag in the Chuck Jones cartoon "Ali Baba Bunny" that was also edited on CBS) was cut.
