The altar worship of Baal at Mt. Carmel has several errors. First, three of the Baal priests, the ones wearing green, yellow and purple, are seen dancing with the High Priest of Baal, but then at one point the Baal Priest wearing pink has somehow joined the group, then he disappears. Then when the three collapse from exhaustion, the purple-clothed priest collapses in the center with the green-clothed one on top of him, and the yellow-clothed one falls on the circular indentation with his face towards the camera, but then when the High Priest of Baal climbs up on the altar, the yellow and purple clothed priests have their colors swapped, and then in the shot when the High Priest falls off the alter, the now purple-clothed priest is lying in a different position.
When the servant flinches after Ahab yells at him to use all the water, a spot of paint appears on the celluloid used to animate the film on the lower right part of the screen.
When the High Priest of Baal climbs up on the altar exhausted and moans "Oh Powerful Baal...send down your fire...show them that...that you are God..." the celluloid of the unconscious Baal Priests can be seen flapping against the screen, most likely an animation photographer's error.
