In Germany, in the German-language dubbed version, audiences saw only Jim Brown throwing hand grenades into the airshafts at the chateau. The scenes showing grenades being dumped into, and gasoline being poured into, the airshafts were cut.
In Spain, the dubbed version changed John Cassavetes's character's name "Franko" into "Franchi", as that country was then under the dictatorship of General Francisco Franco.
