1954–1962: acting debut and Rawhide

According to a CBS press release for Rawhide, Universal-International 's camera crew was shooting in Fort Ord when an enterprising assistant spotted Eastwood and invited him to meet the director, although this is disputed by Eastwood's unauthorized biographer, Patrick McGilligan. According to Eastwood's official biography, the key figure was a man named Chuck Hill, who was stationed in Fort Ord and had contacts in Hollywood. While in Los Angeles, Hill became reacquainted with Eastwood and managed to sneak him into a Universal studio, where he introduced him to cameraman Irving Glassberg. Glassberg arranged for an audition under Arthur Lubin, who, although very impressed with Eastwood's appearance and stature, then 6 ft 4 in (193 cm), disapproved of his acting, remarking, "He was quite amateurish. He didn't know which way to turn or which way to go or do anything." Lubin suggested that he attend drama classes and arranged for Eastwood's initial contract in April 1954, at $100 per week. After signing, Eastwood was initially criticized for his stiff manner and delivering his lines through his teeth, a lifelong trademark.

In May 1954, Eastwood made his first real audition for Six Bridges to Cross, but was rejected by Joseph Pevney. After many unsuccessful auditions, he was eventually given a minor role by director Jack Arnold in Revenge of the Creature (1955), a sequel to the recently released Creature from the Black Lagoon. In September 1954, Eastwood worked for three weeks on Arthur Lubin's Lady Godiva of Coventry, won a role in February 1955, playing "Jonesy", a sailor in Francis in the Navy and appeared uncredited in another Jack Arnold film, Tarantula, where he played a squadron pilot. In May 1955, Eastwood put four hours' work into the film Never Say Goodbye and had a minor uncredited role as a ranch hand (his first western film) in August 1955 with Law Man, also known as Star in the Dust, starring John Agar and Mamie Van Doren. Universal presented him with his first television role on July 2, 1955, on NBC 's Allen in Movieland, which starred comedian Steve Allen, actor Tony Curtis, and swing musician Benny Goodman. Although he continued to develop as an actor, Universal terminated his contract on October 23, 1955.

Eastwood joined the Marsh Agency, and although Lubin landed him his biggest role to date in The First Traveling Saleslady (1956) and later hired him for Escapade in Japan (1957), without a formal contract, Eastwood was struggling. On his financial advisor Irving Leonard 's advice, he switched to the Kumin-Olenick Agency in 1956 and Mitchell Gertz in 1957. He landed several small roles in 1956 as a temperamental army officer for a segment of ABC 's Reader's Digest series, and as a motorcycle gang member on a Highway Patrol episode. In 1957, Eastwood played a cadet in West Point series and a suicidal gold prospector on Death Valley Days.

In 1958, he played a Navy lieutenant in a segment of Navy Log and in early 1959 made a notable guest appearance as Red Hardigan on Maverick opposite James Garner as a cowardly villain intent on marrying a rich girl for money. Eastwood had a small part as an aviator in Lafayette Escadrille (1958) and played a major role as an ex-renegade of the Confederacy in Ambush at Cimarron Pass (also 1958): a film that Eastwood considers the low point of his career.

In 1958, Eastwood was cast as Rowdy Yates in the CBS hour-long western series Rawhide, the career breakthrough he had long sought. Eastwood was not especially happy with his character; Eastwood was almost 30, and Rowdy was too young and cloddish for his comfort. Filming began in Arizona in the summer of 1958. It took just three weeks for Rawhide to reach the top 20 in TV ratings and, although it never won an Emmy, it was a major success for several years, and peaked at number six in the ratings from October 1960 to April 1961. The Rawhide years (1959–65) were some of the most grueling of Eastwood's career, often filming six days a week for an average of 12 hours a day, but some directors still criticized him for not working hard enough. By late 1963, Rawhide was beginning to decline in the ratings and lacked freshness in the scripts; it was canceled in the middle of the 1965–66 season. Eastwood made his first attempt at directing when he filmed several trailers for the show, but was unable to convince producers to let him direct an episode. In the show's first season, Eastwood earned $750 an episode. At the time of Rawhide ' s cancellation, he received $119,000 an episode as severance pay.
