Character actor Jim Davis is known for his many westerns but is best remembered in the role of Jock Ewing on the CBS TV series Dallas. Throughout the 1950s Davis worked steadily in films, but when his career stalled in the 1960s, he found lots of work in television. Following the death of his daughter in 1970, he threw himself into his career, acting in a number of films in the 1970s and landing a plum role on Dallas. Davis died of cancer in April 1981 at the age of 71.
