Visible crew/equipment: When Angel Eyes sits down at the dinner table in his first scene, there is a small unlit lantern hanging on the wall near his head, and unexplainable light sources reflected on it. (00:09:35)

Other mistake: When Blondie and Tuco are talking about telling each other the location of the money, a car drives by in the background. In the shot where both Blondie and Tuco are visible, watch the top right in the trees in between the pillars supporting the bridge.
Tuco: I'll kill you.
Man With No Name: If you do that... You'll always be poor... Just like the greasy rat you are.
Chosen answer: Tuco knew he had a better chance at survival (and the gold) by playing along with Blondie and keeping his balance on the cross, hoping Blondie does not miss the rope when he shoots. This final, deadly game was preferable to being shot outright by Blondie and dying a poor man.

Tuco had no idea that Blondie's intention was to shoot the rope and let him live.
