Corrected entry: When the water crashes through the dome, although this is a very impressive effect, look at the hole the water comes through. You can see the peak of the set and a bit of the huge bucket used to tip the water.
Corrected entry: When the grand staircase area is sinking, a close-up reveals the clock being covered with water. Seconds later a long shot shows John Jacob Astor hanging on to a pillar and the clock is visible (behind him) with a foot of water still to go before water comes crashing through the dome.
Corrected entry: After Tommy is shot and Fabrizio puts on his life jacket and ends up in the water, water from a porthole is sucking people into the ship, Fabrizio is sucked near the porthole. He stops himself by placing one hand on the side of the window, and one on the top of the window. Suddenly it's a stuntman, with heavy black gloves and long sleeves. Fabrizio saves himself, and it's his arm and hand once more.
Corrected entry: Haven't you noticed that not even once the second class passengers are mentioned? Even when the woman in the third class says, "When they're finished putting the first class people in the boats, then they'll start with us." Second class'd go before third.
Corrected entry: When Cal is chasing Jack and Rose through the dining room and shooting at them, the windows in the background have sunlight shining through. Since the Titanic sunk in the middle of the night, no light should be coming through the windows. Hard to believe the crew took hours to light a "night" scene and didn't notice the sunbeams in it. This mistake can also be seen in a still photo in various movie tie-in books. (02:15:30)
Corrected entry: There is a dancing scene in a ballroom with a lot of mirrors, and when you look closely, you can see the filmcrew in one of the mirrors.
Corrected entry: When they spot the iceberg from the crows nest, if you look closely on its left there is a large vertical stick of ice silhouetted in the darkness. It's very easy to spot, although when the ship gets closer the vertical stick disappears. Surely that's not possible.
Corrected entry: Right after Jack and Rose kiss on the front of the boat, the camera slowly backs up to behind the boat so you can see the entire thing. It is a continuous motion for the camera, and Jack and Rose are still at the front of the boat for most of the shot, but if you keep your eye on them, they disappear by the time the camera gets to the back of the boat...
