The actor Don Murray, who has died aged 94, made his big screen debut in 1956 opposite Marilyn Monroe in Bus Stop. His performance as the gangling, wide-eyed cowboy who falls for a saloon bar singer earned him an Oscar nomination as best supporting actor and a Bafta nomination as most promising newcomer. Monroe was superb as Chérie and Murray as Beauregard, besotted and eager to marry, made the perfect foil.
His career continued strongly in 1957 with The Bachelor Party, in which he played a married man unhappy about the dubious happenings at a stag party, and A Hatful of Rain, as a Korean war veteran addicted to heroin. The director, Fred Zinnemann, described it as “the grimmest film I ever made”. Murray’s performance displayed the commitment that was to characterise much of his work. Few actors have allowed their moral beliefs and sociopolitical concerns to affect their careers so markedly.
