The repeated casting of the same actors, generally for similar roles, is typical for the 60s Wallace movies as well. Among the most popular lead protagonists are Joachim Fuchsberger, Heinz Drache and Siegfried Lowitz. Shady characters were mostly played by Fritz Rasp, Pinkas Braun, Harry Wüstenhagen and especially Klaus Kinski, while comic relief was offered by Eddi Arent, Siegfried Schürenberg and later Hubert von Meyerinck or Chris Howland. Additionally, well-known film and stage actors like Elisabeth Flickenschildt, Gert Fröbe, Dieter Borsche, Lil Dagover, Karin Dor and Rudolf Forster repeatedly appeared in important guest roles.
