During the opening credits, Esteban is seen controlling the golden condor using 2 control levers. However, during the episodes proper, he only uses one (the condor just has one, shaped like a cobra).
Episode 11 in the US version contains a slight time cut, missing a close up scene of a soldier in the temple doorway as it is collapsing. Episode 1 in the British version starts immediately at the narration "It is the year 1532" rather than showing a god shot of Barcelona. Episode 32 in the British, Polish, and German versions all contain a scene cut. After Papa Camayo gets shot by the Olmec, Pedro and Sancho hit him with a log. However, this scene continues with them saying "Here's your reward" and then using his back as a pivot for a see saw. It was probably removed for violence. Episode 36 in the British version is missing the opening sequence that shows the Olmec flying machine using the secret weapon to kill a bunch of Mayans.
