Indiana native Charles Arnt attended Princeton University, where he was president of the Triangle Club and where he earned a geological engineering degree. Short, balding and with an air of perpetual suspicion concerning his fellow man, Arnt seemed far older than his 30 years when he was featured in the original Broadway production of Knickerbocker Holiday. In the movies, Arnt was often cast as snoopy clerks, inquisitive next-door neighbors or curious bystanders. Charles Arnt was seen in such films as The Falcon's Brother (1942), The Great Gildersleeve (1943) and That Wonderful Urge (1948); he also played one top-billed lead, as an obsessive art dealer in PRC's Dangerous Intruder (1946).
