Smashing windows
When the Captain stands on the bridge, and he sees the water smashing through the glass as it gives in, it is one of the most emotional scenes in the movie. Knowing that this was a potent shot, Cameron reshot the scenario using a variety of camera angles to provide a dramatic effect. Every time it was photographed, though, the water entered differently.
As a result, whereas in one view, the windows shatter in the sequence one, two, three, and four, in the subsequent angle, the sequence is reversed and reads one, two, four, and three.
