The Mexican emissary and former acrobat Luis Dominguez (Nino Castelnuovo) comes to America to summon the outlaw Mesito (Bud Spencer) that is working in a farm; the gambler and expert in dynamite Capt. Nicolas Augustus (James Daly); and the mute Japanese Samurai (Tetsuro Tamba) that has a great skill with knives under the call of their acquaintance Dutchman (Peter Graves) from Mexico with the promise of a reward of one thousand dollar for each one. When the five men reunite, Dutchman explains that there is a big, fat, juice train transporting five hundred thousand dollar for the Dictator General Huerta and the leader of the revolutionary forces proposed them to rob the train to support the peasants and the revolution. However, the plan seems to be impossible to be accomplished since the train is protected by an army, but the five men decide to rob the gold and double-cross the revolutionaries. But some of them have hidden intentions
"Un Esercito di Cinque Uomini" is a "spaguetti" western at best. The story, with screenplay of Dario Argento, is full of action and betrayals developed in a fast pace and with a great camera work. The result is a funny and entertaining movie, with situations resolved in the most impossible way. My vote is seven.
Title (Brazil): "Exército de 5 Homens" ("Five Man Army")
