Continuity mistake: While Batman is fighting Black Manta, he dives over as the bad guy blows a car into the air. The car is a light blue color and falls over on Batman. The next shot as Black Manta is walking towards it, the car has turned to a light orange color. Moments later when Batman crawls out of that car, it is back to being light blue. The car it lies on also changes from purple to orange.
