When Velasquez is in the vault with the statues and treasures, he stops in front of the first statue and it is brightly lit by the match he is holding. When he moves away and continues into the vault, the statue stays lit.
When Velasquez is in the cave vault the first time, he walks around looking at the treasures by holding a candle. He is lit by a studio spotlight that is supposed to mimic the candlelight, but it is much too bright for a candle, and the light shakes a bit, as if it is a heavy, handheld light. There is also a delay in moving the light when Velasquez moves.
