The film Old Shatterhand (known as Apaches' Last Battle in the UK) is a very successful Eurowestern based on the character Old Shatterhand invented by German novelist Karl May. It is a West German CCC Film production co-produced with French, Italian, and Yugoslav companies and filmed in 70mm. Financed with roughly DM5,000,000, the film was the most expensive Karl May western. Composer Riz Ortolani used a chorus for his film score. Part of the set for this production was the Plitvice Lakes National Park in Croatia.
