What did Frank Capra mean by his “one man, one film” theory?

Frank Capra’s "one man, one film" theory was rooted in his firm belief that a director should be responsible for every aspect of their projects. By advocating for this approach, Capra sought to ensure that a single creative vision guided the entire filmmaking process, from conception to completion.1

During his career, particularly while working as a producer-director at Columbia Pictures, Capra operated his own production unit, which granted him the creative freedom necessary to implement this philosophy. As a prominent figure in the industry and a leader of the Screen Directors’ Guild, he actively fought for this level of creative autonomy for other directors as well. This theory reflects his commitment to individual expression, a value that became a hallmark of both his filmmaking creed and the idealistic, courageous heroes often featured in his work.1
