The film is a red western made by DEFA, the state-owned East German studio.[1] It is part of a popular string of films starring the Yugoslav actor Gojko Mitić which, in line with the policies of Communist East Germany, attempted to present a more critical, but also more realistic, view of American expansion to the West than was characterized by Hollywood. The film, along with others, was also made partly in response to the successful series of Karl May films made in West Germany.[2]
