In the scene where Ben Affleck (Rafe) and Kate Beckinsale (Evelyn) are in New York where the Queen Mary is docked, after they steal the police boat, you can see as they pull up to the ship that the waterline (a white line seperating the black and red painted sections of the hull) is about 10 or 15 feet above the actual waterline. They had to film it like that because the Queen Mary is now docked in Long Beach, and it has been emptied of alot of nonessential weight. removal of all the boiler rooms, the forward engine room, both turbo generator rooms, the ship stabilisers and the water softening plant, so they could turn it into a musem/ hotel. But in 1940, when the Queen Mary was sailing, she would have been heavier, and the water line would have been at that white mark. You would think some simple CGI would have fixed that.
