Revealing: (DVD timings) The band decide to go their separate ways, just before the ship sinks. As they are seen departing, the lead violinist strikes up a solo - I think it'd be 'Nearer My God to Thee' or so the legend goes. A fraction of a second before he does, watch the second violinist - he disappears off to the right of the shot at first, then reappears near the side of the ship - he is obviously awaiting his cue as he turns round too early, i.e. before the lead strikes the first note, then turns away again.

Continuity: In the scene where Jack is handcuffed water starts running into the room the desk. At that moment the desk, which had been out of reach before, is moved closer to Jack and standing diagonally, so that Jack can climb on it. This happens before things get moved around by water or gravity.

Factual error: The both times the fireplace in the first class lounge is seen there is nothing on the mantle piece. But in photos of the actual lounge there is a statue on the mantle called "Artemis of Versailles" which was a small copy of the original in the Louvre, Paris. The statue was even photographed on the ocean floor when the Titanic was found, but there is no statue in James Cameron's movie.

Continuity: In the scene where Ruth boards the ship she walks on the plank followed by her maid. Cal and Rose are not seen in the scene. In the next scene Ruth is entering the ship followed by Cal and Rose and then the maid is in view again.

Continuity: At the beginning when Jack and Fabrizio go to the front of the ship, you can see the anchor section at the front, yet when Jack is waiting for Rose, the camera pans up, and its a completely different design, than from the first look at the beginning.

Audio problem: When the Captain is watching the overturned boat trying to be launched, there is a crew member working on the davit, causing it to make a rapid clicking noise. But soon after the noise stops, the crewmember is still turning.

Continuity: In the scene where Rose attempts suicide she is holding on the railing while standing on the outside. In some shots the end of her black lacy robe is under her left hand, in some it isn't.

Continuity: On the day after Rose got the diamond she and Jack talk a walk on the deck. From the light on the deck you can tell that the sun is still fairly high up. When the camera angle changes and we see them from behind the deck is in the dark, and the sun is falling in almost horizontal. When they sit down to look at Jack's drawings the sun is higher again.

Continuity: When the old Rose arrives on the Keldish, she is unloaded from the helicopter sitting in her wheelchair. The two pilots are helping from above, but afterwards they disappear inside the helicopter from one shot to the next, which is too fast as the rotor noise suggests continuity.

Factual error: Jack (Leonardo DiCaprio) was handcuffed with old English Hiatt's Darby Handcuffs (type 104). This is historically correct. But the key for these handcuffs identifies them as modern reproductions, because it had a flat top and was "checkered". The old keys had an oval and smooth (only marked with "Hiatt" and a number) top. The handcuffs used in the film were not from 1912.

Audio problem: During the scene where Jack and Rose are walking around the ship and talking and Rose is telling him about her upcoming fears about the wedding, a frontal camera shot on Jack shows him asking her "It's a simple question, do you love the guy or not?". Jack finishes his sentence here, but about a second later, a rear camera shot of Jack (now also facing Rose) shows that his jawline and lips are moving and finishing the words "or not".

Continuity: When Jack and Rose are dancing on the 3rd class level, Rose takes her shoes off and looks down at her feet, in the following shot she is looking at Jack, and the shot after she looks at Jack again.

Deliberate "mistake": Even though the movie uses the correct number of rockets, the timing is awful. The last rocket was fired at 1:40 AM at the latest. In the movie, the last rocket is fired when the last boat to be lowered on the davits leaves (the one Rose gets, and jumps off of). This would make it 2:05 in James Cameron's Titanic time. It was probably changed to add more drama to that heart-throbbing scene...

Factual error: The radio system in use at that time was based on spark transmission and we should never have heard a nice clean transmission of Morse code SOS or CQD beeps.

Continuity: In the scene the captain looks at the bridge sinking, the water level is by the middle of the helm wheel. In the next, from the other entrance, the level is lower than that, and in the next it's again by the middle of the wheel, which is also turned to a different position.

Continuity: In the scene where Jack meets Rose for dinner and Cal says "you almost look a gentleman," take a look at Rose's facial expression beforehand. The shot changes from side view to front view several times and her expression changes from smiling to normal at each change of shot in under 15 seconds.

Continuity: When Tommy Ryan, one of Jacks ship friends, is trying to get to the top deck, but is stopped by metal guard rails, at the beginning of the scene he has his right hand on the rail, then in the next shot he has his left hand on the rail.

Continuity: When Rose and Jack beg a steward to open the gate for them while the water is rising, the steward drops the keys and runs away. There are two shots of the keys on the chain lying in the water arranged in totally different ways (the difference is not caused by the water flow as the keys are not moving in either shot).

Continuity: When Tommy begs the steward to open the gate he is reaching with his right arm through the gate, holding on to a bar. When the camera angle changes the arm is hanging down.

Revealing: Throughout the whole movie, you can see the outline of hills in the background, even though the Titanic sank in the middle of the Atlantic.
