This Old Cub is a 2004 documentary film. The film is centered on former Chicago Cubs third baseman Ron Santo and both his playing days and his battle against diabetes. The film was written, co-produced, and directed by Santo's son Jeff. It is often mentioned during Cub game broadcasts by Pat Hughes, who was Santo's partner in the WGN Radio booth. The film was a gift from Jeff to his father as a part of the "Ron Santo Day" celebration that season after Santo had both his legs amputated and had just missed induction into the MLB Hall of Fame a few months earlier. A portion of all proceeds from the release of This Old Cub are donated to the Juvenile Diabetes Research Foundation. The film has raised over a half-million dollars for the JDRF. Cub first baseman Ernie Banks, Gary Sinise, Bill Murray, former Chicago Bears linebacker Doug Buffone, and many others are interviewed in the film, which is narrated by actor Joe Mantegna.
