Jules Greenbaum was a German pioneering film producer. He founded the production companies Deutsche Bioscope, Deutsche Vitascope and Greenbaum-Film and was a dominant figure in German cinema in the years before the First World War. He is also known for his early experiments with sound films around twenty years before the success of The Jazz Singer made them a more established feature of cinema.

Continental-Kunstfilm GmbH was a short-lived German film production company based in Berlin, formed in February 1912 by Walter Schmidthässler and Max Rittberger. A large number of Continental-Kunstfilm's productions are now probably lost, although some significant films have survived into the 21st century.
