Clint Eastwood, b. May 1930, San Francisco, California, is an American movie actor who emerged as one of the most popular Hollywood stars of the 1960s. He then went on to become a prolific director-producer.

In 1940, Eastwood lived in Piedmont, California. During the Korean War, he was drafted and stationed in California. Following his discharge from the army in 1953, he lived in Hollywood. A screen test with Universal in 1954 netted him a 40-week contract. He got bit parts in such movies as "Tarantula" (1955) and "Revenge of the Creature" (1955). He next was in several TV series before he got his big break in 1959 as Rowdy Yates in the TV western "Rawhide" (1959–65).

Eastwood subsequently went on to achieved international stardom. He was The Man with No Name—a fearless and stoic gunfighter—in three Italian westerns (“spaghetti westerns”) directed by Sergio Leone: "A Fistful of Dollars" (1964), "For a Few Dollars More" (1965), and "The Good, the Bad and the Ugly" (1966). These established Eastwood as a box-office icon.
