• There is crew or equipment reflected in Rose's TV.
• Jack wins his ticket by beating 2 pair with a full house. However, when we first see Jack's hand, he has nothing that could be made into a full house, and only draws one card.
• A strip of desert is visible between the dock and the Titanic when docked at Southampton.
• When Captain Smith orders, "Take her to sea, Mr. Murdoch -- let's stretch her legs", they are standing to the right of the wheelhouse looking forward with the sun coming from their left. When Murdoch walks into the wheelhouse to carry out the order, the sun is behind him.
• The draft markings on the Titanic's bow when Jack looks at the dolphins later change size and position.
• Jack claims to have gone ice fishing on Lake Wissota, which wasn't created until five years after the Titanic sank.
• Jack claims to have visited the Santa Monica Pier, which did not begin construction until 1916.
• The pipe frames supporting the third class berths have set-screw speed rail fittings, not developed until 1946.
• Margaret Brown was not referred to as "Molly" until after her death. {After the sinking the suvivors were mobbed by newspaper reporters. She was asked "How did YOU survive?" and her response was a simple "How could I not? I am the unsinkable Molly Brown".
• In the scene where Jack is teaching Rose to spit, there is no spit on his chin as he starts to turn around to face the ladies, but by the time he has completed his turn he has some on his chin.
• The painting over the fireplace in the Titanic's first class smoking lounge in the film depicts New York Harbor, which was actually the painting on the Titanic's sister ship, "Olympic". The painter, Norman Wilkinson, had provided a scene of Plymouth Harbor for Titanic, but no pictures of this work survived.
• A closeup of Captain Smith reveals that he is wearing contact lenses.
• The main characters have lunch in the Palm Court/Veranda on A Deck. These were not used for dining, although passengers could order tea or a small snack.
• Cal orders lamb with mint sauce for himself and Rose. Lamb was only available for dinner on the ship, while mutton was reserved for lunch. The lamb was prepared in the D-Deck galley and would not have been served in the Palm Court.
• While Jack and Rose are walking on the promenade the day after he rescues her, a small hill with a building on it is visible over Jack's shoulder and above the ship.
• The button on the left side of Jack's borrowed jacket is a "Kingsdrew" button, first made in 1922.
• Jack takes Rose and Molly's arms to go into dinner. They start walking, but in the next shot they are still standing apart.
• There is crew or equipment reflected in the glass door opened for Jack as he enters the dining room.
• The worship services held at 10:30 on Sunday April 14th, 1912, in the First Class Dining Room were open to all passengers of the ship.
• "Almighty Father Strong To Save" is sung during the worship service; the two verses used in the film were written by Robert Nelson Spencer in 1937.
• During the scene when Rose "flies" from the ship's bow, the sunlight is clearly falling almost exactly straight across the ship from left to right. On the evening of the 14th, the ship would be steaming somewhere between WSW and SW; the lighting in the movie would indicate that the sun is between SSE and SE, when it actually would have been between W and WNW.
• In the same shot, the faces of Jack and Rose are lit from a different angle, though still from the left.
• The length of Rose's fingernails throughout the movie changes.
• The hands sketching Rose are clearly too old to belong to Jack. {They actually belong to director James Cameron.}
• Workers in the Titanic's engine room had to wear thick protective clothing to shield them from the heat generated by the engines.
• The gauges in the engine room are fitted with sweated tubing fittings, a plumbing technique not available when the ship was constructed. The fittings should have been threaded brass.
• There was no door between boiler room 6 and the cargo area {and no access to any but authorized crew}. If there had been a door, it would have entered the third cargo area aft, not the one where the Renault was stored.
• There is crew or equipment reflected in a brass panel on the front of the Renault that Jack and Rose find in the cargo hold.
• The disaster message that the radio operator starts clicking out on the telegraph key is not intelligible Morse code.
• When Captain Smith enters the wheelhouse, the ship's telegraph is set to "Full Reverse" instead of "All Stop".
• The sea water would be at or below freezing point, yet characters rarely display discomfort or disablement from being immersed.
• Jack is supposedly held prisoner in the Master-at-Arms' office, which is depicted as having a porthole. On the Titanic, this room was an interior room and hence would have no portholes.
• That porthole is shown to be several feet below water, yet in a shot from inside the room, the surface of the water is visible inches above the porthole.
• It is impossible for voices to echo in the middle of the North Atlantic unless there is a large, flat object like a ship nearby.
• We are shown a shot of Rose's view of the Statue of Liberty from a ship, yet to obtain a view as indicated she would have to be on land.
• When Rose hands Jack the dime for the picture he did of her, it's a dime that wouldn't have been minted until after Titanic sunk. The dime was from nowadays and had Eisenhower's face but Eisenhower wasn't around till after Titanic sunk.
• The middle propeller was not used to move the ship away from the dock.
• Quartermaster Rowe fired the distress rockets, and was afterwards put in charge of the lifeboat where Bruce Ismay escaped. In the movie, Rowe can be seen firing rockets while Ismay's boat is lowered.
• Lifeboat 14 did not have flashlights when it returned for survivors - this was known by James Cameron, but he needed some light and this was the best solution.
• It's been stated that the portrait of fictional character Rose could not have been preserved. However, paper objects have been salvaged from the wreck. While paper on its own has disappeared, pieces of paper in leather bags and wallets have been preserved. Since the drawing was placed in a leather pouch, it could very well have been preserved.
• The tugs that assisted Titanic at Southampton belonged to the company known today as Red Funnel Line. In 1912, they had a different name and a different color scheme, and this color scheme is correctly shown in the movie.
• The fourth funnel on Titanic has always been a favorite when errors are pointed out. Only funnels 1-3 were connected to the engines, so they are the only ones that should be shown with massive amounts of smoke coming out. The fourth funnel was connected to the kitchen, and since they used coal ovens, there would be quite a lot of smoke there too. In this movie, it can easily be seen that the amount of smoke coming from the fourth funnel is much smaller than from the three others, giving a very accurate depiction of the ship.
• The orders given by 1st Officer Murdoch, "Hard a' starboard" and "Hard a' port", are thought by many to be wrong. They are in fact correct - the orders are from a time when ships were controlled by tillers rather than wheels, and this would be laid over in the opposite direction. Thus, "Hard a' starboard" would turn the ship to port and vice versa. That these were in fact the orders given is confirmed in the Senate hearings. Hitchins, who was at the wheel, survived and gave testimony.
• Which was the last song played by the band? Most serious researchers believe that it was the "Song d'Autumne." Harold Bride stated that the band played "Autumne," and this was for a long time believed to be the Episcopal hymn of that name, but the hugely popular "Song d'Autumne" is a much more likely candidate. However, several survivors have claimed that the last song played was "Nearer, My God, to Thee." When making the movie, Cameron had to decide whether to follow Bride's testimony, or the testimony given by the majority of the survivors. In view of the fact that the words "Nearer, My God, to Thee" are inscribed on Bandmaster Hartley's tombstone, and that this has always been the last song in popular tradition, his choice of playing "Nearer, My God, to Thee" is quite understandable. Cameron chose the American version of the melody, composed by Lowell Mason in 1856 - some survivors have stated that it was the English version that was played, while others name the version used in the movie.
• The suicide of 1st Officer Murdoch is a subject of great controversy. There are two independent reports that an officer shot one or more passengers, gave a military salute and then shot himself, as shown in the movie. The reports do not, however, state that this was Murdoch. As with the last song, this should be considered part of the artistic licence that a director can and must allow himself, rather than an error. No matter what one thinks of this decision, the scene is consistent with known facts - when bodies were picked up, none were found to have bullet wounds, and in the movie the lifejacket worn by the man who was shot was removed, and Murdoch did not wear a vest, which makes it likely that they were both dragged down by the ship.
• Many presume that it is impossible for persons in unfrozen water to have ice form in their hair. The small amounts of sea water in a person's hair would have frozen at higher temperatures than the sea itself, so this is not only possible, but likely.
• The lifeboats are labelled "S.S. Titanic," while the ship itself is called "R.M.S. Titanic." Photographs show that this is the correct labelling. Even though a ship is designated as "R.M.S.," it is still "S.S." if it is steam-powered, so there would be no need for White Star Line to change the labelling.
