- Enforced Method Acting: As there were no water tanks in studios big enough to accommodate the sets, outdoor scenes were shot in an open-air swimming pool. In November; none of the actors wanted to have to jump in. Kenneth Moore wrote:
"I would have to set an example. I leaped. Never have I experienced such cold in all my life. It was like jumping into a deep freeze just like the people did on the actual Titanic. The shock of the cold water forced the breath out of my lungs. My heart seemed to stop beating. I felt crushed, unable to think. I had rigor mortis... without the mortis. And then I surfaced, spat out the dirty water and, gasping for breath, found my voice. 'Stop!' I shouted. 'Don't listen to me! It's bloody awful! Stay where you are!' But it was too late as the extras followed suit."

- History Marches On: Titanic is shown going down in one piece. Since the discovery of the wreck in 1985, it's generally accepted that the ship broke in two before it sank.
- Throw It In: The ominous creaking noises the ship makes as it founders were actually made by the set as it was tilted into position.
