Other mistake: During the opening sequence there is a shot of a muddy river where we are shown the credits for Director of Photography, Camera, Sound, Film Editor etc. When "Camera" is credited there is a number 2 next to it, that is the order in which the credit appears, but none of the other credits are numbered. (00:06:20)
Suggested correction: That's not a mistake. Fransisco Joán and Orlando Macchiavello were second cinematographers (2. Kamera in the original German film credits).
