The three lead actors Pierre Brice, Lex Barker and Stewart Granger were very familiar to audiences in German speaking countries, because of their appearances as the heroes in numerous films based on the novels of Karl May. Pierre Brice had played the iconic title character in La valle dei lunghi coltelli (1963) and the sequels, Lex Barker had played Old Shatterhand in the same film and some of it's sequels as well as the heroes in the various other adventure films based on Karl May novels, and Stewart Granger had played Old Surehand in some of the Winnetou sequels. While Pierre Brice had worked repeatedly with both Lex Barker and Stewart Granger, this is the first and only film featuring all three actors together.
