Our Mr. Sun is a 1956 one-hour American television film in Technicolor written, produced, and directed by Frank Capra. It is a documentary that explains how the Sun works and how it also plays a huge part in human life. It was first broadcast on television by CBS in 1956. Our Mr. Sun, and a companion film Hemo the Magnificent (about blood circulation), were popular favorites for showing in primary and secondary school science classrooms from the late 1950s until the early 1980s. The film is currently available on DVD with another Frank C. Baxter film The Strange Case of the Cosmic Rays (1957).
