Continuity mistake: We see Mr Andrew walking through the 1st class cabins just after hitting the iceberg. He has 4 blueprint rolls under his arms. We then see him out on deck while discussing the situation with a few other men and the rolls have gone. As he gets to the office with Captain Smith he has the rolls again. (01:39:20)
Continuity mistake: When we see Jack and Fabrizo at the front of the ship, in one shot we see the wind blowing Jack's hair and jacket. In the next shot it's not. (00:29:50)
Continuity mistake: When Jack looks through the porthole (which is full submerged underwater) while cuffed, he looks over his left shoulder which is facing the hull of the ship. He then turns his head which cuts to him inside the room, his left shoulder is now facing away from the hull of the ship, towards the door. The shot of him looking through the porthole is possibly a reversed shot.
Answer: Yes, it was. At the time, the big cruise lines were all trying to outdo each other with the largest and most opulent cruise ships. The Olympic class ships were the White Star Line's entry in the size race, with Olympic, the first built, taking the title in 1911, before losing it to her sister ship, the Titanic, the following year.
