Theatre-Five (aka Theater-Five or Theatre 5) was a radio drama series, presented by ABC between 1964 and 1965. The series used an anthology format, presented a number of short (20-minute) radio plays, across a number of genres, a number of which reflected topical issues contemporary with its airing.
Writers for the show varied, as did actors, although a principal cast included George O. Petrie, Brett Morrison, Jackson Beck, Robert Dryden, Elliott Reid, Court Benson, Cliff Carpenter, and Bryna Raeburn. The show's 1965 run featured several well-known actors, including an early role for James Earl Jones ("Incident on US 1"), a pre-"M*A*S*H" Alan Alda ("A Bad Day's Work"), and Ed Begley ("The Pigeon") three years after his Academy Award win. Another Theatre-Five actor was Romeo Muller, who also wrote stories for the series but who became best known for his work with Rankin/Bass Productions such as Rudolph the Red-Nosed Reindeer (TV special).
