Born in October 1934, Buchanan made his first listed appearance late, at the age of 31 in the 1975 film C.I.A. Secret Story, directed by the arch provocateur Giuseppe Ferrara. Before this, however, he had already been active in Italian cinema for almost half a decade – much like many anonymous American adventurers – as a stuntman and extra, sometimes using the name Buck West. His part in C.I.A. Secret Story was largely insignificant, and although he played a named character in Edward Dmytryk’s big-budget spy film The Human Factor he was just one of a number of jobbing Americans buried deep in the credits (including a very young Danny Huston, who was only thirteen at the time). More fleeting appearances followed – in Pupi Avati’s Bordella, Dino Risi’s Telefoni bianchi – before he secured his first major role in Mino Guerrini’s comedy Vinella e Don Pezzotta, based on a successful radio play and starring Giorgio Bracardi. A religious parody, the third billed Buchanan played Padre Splendid, a modernizing priest sent to Italy from the States.
