In the 1940, Francis headed for Hollywood to start an acting career. His plans were initially interrupted by the Second World War, during which he served in the medical detachment of the 49th Field Artillery Battalion, 7th Infantry Division. He played minor parts in several films from the late 1940s to early 1970s.
In 1959, Francis formed a partnership with Anthony Cardoza, a welder by trade, and together they created three films: The Beast of Yucca Flats (1961), The Skydivers (1963) and Red Zone Cuba (1966). Francis wrote and directed the films, while Cardoza handled production duties.
