British actor who won an Oscar from the Motion Picture Academy of Arts and Sciences for his role in Ben Hur (1959) and brought energy and ebullience to such character parts as Professor Welch in Lucky Jim (1957) and Squire Western in Tom Jones (1963). Although as a film actor his comedy had a savage bite that raised it above the level of slapstick, it was on stage that he was able to exhibit the full range of his talent.

After army service during World War II, Griffith joined the Shakespeare Company (now the Royal Shakespeare Company) and appeared in many notable productions, including Love's Labour's Lost, Dr. Faustus, and The Caucasian Chalk Circle. He played King Lear in 1949 and Falstaff in 1964, the latter perhaps his most memorable performance. He also won much acclaim for his roles in Jean Anouilh's The Waltz of the Toreadors in 1956 and the New York City production of Look Homeward, Angel in the following year. Griffith, who began his career as a bank clerk, was made an honorary doctor of literature of the University of Wales in 1965.
