Factual error: When the ship sinks it lamely slips into the water at a low angle. Somewhat of an anti-climax. Contrary to some reports, even at the time the film was made it was known that part of the ship upended at 45 degrees and sank vertically. I discovered this when I listened to an eyewitness account which is a permanent fixture at the British Library.
Factual error: At the very end, there is a shot onboard the rescue boat (that was too late). If you look in the background, you can see the boat is bobbing with the waves, by the way the water is in shot then out, then in, etc. A ship of that size would just break the waves. No way could it bob to the extent it does in the film. A lifeboat you would expect to bob that much but not a ship of that size.Ssiscool
