Gangly actor with a nervous, anxious quality and a good sense of comedy, remembered for his work in TV comedies of the 1960s and early 70s, especially as the perennially frazzled spouse of nose-twitching wife-cum-witch Samantha (Elizabeth Montgomery) on the popular sitcom "Bewitched". Sargent began appearing in light feature fare in the late 1950s including the teen comedy, "Bernardine" (1957) and the Pat Boone musical, "Mardi Gras" (1958). He sometimes played in dramas like "Captain Newman M.D." (1963) but more typically Sargent was cast in supporting roles in "That Touch of Mink" (1962),
