Revealing mistake: The jaguar near the start jumps onto the bar and prowls along it. It knocks over one glass with some force, which shatters, but the second glass is barely tapped by its foot and it smashes to bits too, when it should just have been pushed out of the way.
Continuity mistake: The boat narrowly escapes going over the waterfall and turns down another tributary. In the overhead shot the river here still looks very choppy but when we see everybody on the boat, the water behind them is going very slow.
Continuity mistake: When Joachim is taken to the room where the arrowhead is, his guide has both hands together. A shot later the right one is lowered and the left one is raised. (00:06:17)
Continuity mistake: When Lily is caught in a room she dries the left side of her neck with a handkerchief, but a shot later from the opposite angle her arm is lowered. (00:04:12)
Continuity mistake: After the intro, the scene dissolves into a map that resembles the branches that trapped Aguirre. A shot later the design of the map is different.
Revealing mistake: Frank and Lily are swinging from a vine. As they reach the end of the swing, Frank manages to put one boot heel on the landing, but cannot get his footing to stay there. He lifts his foot repeatedly trying to get a better purchase. Except that as he is barely hanging on, lifting his boot even once would propel him backwards, much less lifting his foot several times without a back swing. He finally loses his purchase on the landing, but not because of the repeated attempts to lift his foot off. (01:09:40)
Continuity mistake: When Lily enters the room to steal the arrowhead, she holds a drawing with her right arm raised. From the opposite angle it's lowered.
Continuity mistake: The first time Lily meets Joachim, he holds a Zulu Iklwa and shows it to her. From the opposite angle the Iklwa is in a different position, and he's repeating the previous movement.
