Or for his breakthrough role in Baby Doll.
He was a film, television and stage actor whose career spanned more than six decades, beginning in the late 1940s. For his performance as Silva Vacarro in Baby Doll, he won a BAFTA Award for Best Newcomer and a Golden Globe nomination. Among his most famous roles are Calvera in The Magnificent Seven (1960), Guido in The Misfits (1961), and Tuco in The Good, the Bad and the Ugly (1966).
Wallach's film debut was in Elia Kazan's controversial 1956 Baby Doll, for which he won the British Academy Film Awards (BAFTA) for "Most Promising Newcomer." He went on to a prolific career in films, although rarely in a starring role. Other early films include The Lineup, The Misfits with Clark Gable and Marilyn Monroe, The Magnificent Seven with Yul Brynner and Steve McQueen, Lord Jim with Peter O'Toole, a comic role in How to Steal a Million with Audrey Hepburn, and as Tuco (the 'Ugly') in Sergio Leone's The Good, the Bad and the Ugly with Clint Eastwood followed by several other spaghetti westerns, including Ace High. Wallach and Eastwood became friends during the filming of The Good, the Bad and the Ugly and he recalled their off-work time together: "Clint was the tall, silent type. He's the kind where you open up and do all the talking. He smiles and nods and stores it all away in that wonderful calculator of a brain."
