Third and rarest pairing of Terence Hill and Bud Spencer after God Forgives... I Don't (1966) and Ace High (1967), both by director Colizzi, before the Trinity films turned them into Italy's most dubious exports of the Seventies. Hill was given these cold-eyed roles before the more familiar slaparound antics; here he plays a grimy cheroot-huffin' hombre called `Trouble', who enlists a traveling circus (led by Woody Strode and Lionel Stander) to defeat a money-grubbing land baron (Batman's King Tut, Victor Buono). Like all good Spaghetti Westerns, Boot Hill combines claustrophobic visuals and a lumpen left wing philosophy, with the added novelty of the circus backdrop. Bud's almost a supporting player, but thankfully the dumb ox still gets to throw his weight around. Recommended, muchachos.
