Throughout the 1930s, 40s and 50s, several independent film production companies (referred to a "poverty row" studios) turned out hundreds of "B" movies--low-budget feature films that were specifically designed to play the bottom half of the double bills. This handy reference focuses on the output of three of these independents--Grand National (1936-1939), Producers Releasing Corporation (1939-1948), and Screen Guild/Lippert (1945-1955). Here are studio histories and details on all their output (title of movie, director, producer, writer, cast, plot, synopsis, running time, release date, and more). Films are covered chronologically by release date.
