Blam blam blam. That’s 3 movies made virtually back to back. Each of them also only 2-3 months for release after production finished. Oil Prince in August, Winnetou 3 in October and Ild Surehand in December. Rialto never messed around - that’s cos they were backed by Constantiin who could get them distributed immediately.
