devices with the borrowed US Western devices typical for most of the 1963–64 Spaghetti Westerns. For example, in Sergio Corbucci's Minnesota Clay (1964) that appeared two months after A Fistful of Dollars, an American style "tragic gunfighter" hero confronts two evil gangs, one Mexican and one Anglo, and (just as in A Fistful of Dollars) the leader of the latter is the town sheriff. In the same director's Johnny Oro (1966) a traditional Western sheriff and a mixed-race bounty killer are forced into an uneasy alliance when Mexican bandits and Native Americans together assault the town. In A Pistol for Ringo a traditional sheriff commissions a money-oriented hero played by Giuliano Gemma (as deadly but with more pleasing manners than Eastwood's character) to infiltrate a gang of Mexican bandits whose leader is played typically by Fernando Sancho. Further developments of the genre Just like Leone's first Western, the following works in his Dollars Trilogy — For a Few Dollars More (1965) and The Good, the Bad and the Ugly (1966) — strongly influenced the further developments of the genre, as did Sergio Corbucci's Django and Enzo Barboni's two Trinity films, as well as some other successful Spaghetti Westerns. For a Few Dollars More and unstable partnerships After 1965 when Leone's second Western For a Few Dollars More brought a larger box office success, the profession of bounty hunter became the choice of occupation of Spaghetti Western heroes in films like Arizona Colt, Vengeance Is Mine, Ten Thousand Dollars for a Massacre, The Ugly Ones, Dead Men Don't Count and Any Gun Can Play. In The Great Silence and A Minute to Pray, a Second to Die, the heroes instead fight bounty killers. During this era, many heroes and villains in Spaghetti Westerns began carrying a musical watch, after its ingenious use in For a Few Dollars More. Spaghetti Westerns also began featuring a pair of different heroes. In Leone's film Eastwood's character is an unshaven bounty hunter, dressed similarly to his character in A Fistful of Dollars, who enters an unstable partnership with Colonel Mortimer (Lee Van Cleef), an older bounty killer who uses more sophisticated weaponry and wears a suit, and in the end turns out to also be an avenger. In the following years there was a deluge of Spaghetti Westerns with a pair of heroes with (most often) conflicting motives. Examples include: a lawman and an outlaw
