He sold his first teleplay, Bus to Nowhere, in 1950 to the live CBS dramatic anthology program Studio One, for which he wrote Twelve Angry Men four years later. This latter drama, set entirely in a room where a jury is deliberating the fate of a teenage boy accused of murder, was inspired by Rose's Service on just such a trial.The play was later made into the 1957 black-and-white film of the same name.
