Ocean Pictures do Brasil aka Ocean Filmes distributed the movie dubbed in Portuguese under the title "Uma Pistola para Ringo" which is the literal translation of Una pistola per Ringo (1965). The mistake may be due to the fact both films had same director, and mostly the same cast and crew. The distributor made a new edition with both movies in a double set DVD, but not soon enough to prevent USA Filmes from committing the same mistake.
