Other: When a lifeboat is floating upside down, and people are trying to climb onto it, it is not bobbing from side to side at all, as if it was fixed to the bottom of the water.

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.

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.

Continuity: As the ship is about to take its final plunge, a small group of Irish steerage passengers is seen desperately clambering up the rising deck towards the stern. They include the young man seen singing in the third class saloon earlier in the film. Shortly afterwards they are shown again, still on board and awaiting the inevitable. One minute later they have all been miraculously transferred to a lifeboat, in time to witness the ship's passing. As the "Titanic" slips beneath the sea, the aforesaid singer begins reciting the Lord's Prayer.
