Continuity: The day after Jack saved Rose's life, they are walking by the upper deck, and you can see the shadows of the smoke that came out of the smokestacks over them and the ship. However, in the next shot, you can see the shadows have totally disappeared, and in the next shot they reappear, but much more faintly. Also it would be technically impossible for the shadows to be over Jack and Rose, due that the sun is coming at the LEFT side of Jack & Rose, so the smoke shadows should have been at the other side of the ship and not over them.

Factual error: The lake that Jack told Rose he went ice fishing on when she was threatening to jump is Lake Wissota, a man-made lake in Wisconsin near Chippewa Falls (where Jack grew up). The lake was only filled with water in 1918 when a power company built a dam on the Chippewa River, six years after the Titanic sank. (Time)

Continuity: When Jack and Rose are going down with the ship, there is a man holding onto the flagpole. The man's life jacket disappears and reappears. (Time)

Factual error: Rose mentions Austrian psychoanalyst Sigmund Freud's ideas on the male preoccupation with size to Bruce. However this is 1912, and Freud did not publish the work relating to this until 1920 in "The Pleasure Principle." Also, up until 1919, Freud relied solely on data from females. (Time)

Visible crew/equipment: In the scene where Jack comes to the first class door for the first time in his tux you can see a cameraman in the glass door before he enters. (Time)

Factual error: When Rose is arriving in New York half asleep, she looks at the Statue of Liberty, which is the same colour as now (green). But if you visit the statue of liberty, you'll find a plate telling you that the original color was brown, and it took over 35 years for it to change colour. The statue of liberty was placed there in 1886, so in 1912 it should have still been partly brown. Also, the flame was replaced in 1986 (for its 100th anniversary) with a gold flame. The film shows the Statue holding a torch with a gold flame, not the original. (Time)

Continuity: Just as Jack begins to draw naked Rose, he draws a dark line down the center of his paper. In the next shot of the page the line is suddenly much fainter (over to the right) and he is now drawing her face. (Time)

Visible crew/equipment: When Jack and Rose are running from the raging water that is gushing down the hall after them you can see the faces of the stunt doubles through the computer generated ones of Leonardo and Kate. (Time)

Continuity: When Jack and Rose finally come aboard the top of the ship after she rescues him they ask the Colonel if there are any boats left and he says "up that way" The woman on the left, who looks kind of pathetic, is then later seen on the life boat with Molly Brown. (They show her face right after Molly says the line "its your men out there") The life boat with Molly Brown in it was sent out before the scene with the Colonel, meaning that she must have gone on the life boat, swam back onto the ship and then back onto the lifeboat. (Time)

Continuity: When Rose is trying to rescue Jack she spies a fire axe. Smashing all the glass out from the holder she grabs the axe and turns round. The next camera shot shows Rose standing in front of the case with almost all of its glass intact. (Time)

Continuity: In the scene where Jack is persuading Rose not to jump, Jack's shirt collar changes position several times, revealing his white t-shirt from a little to a lot. (Time)

Factual error: In the scene where Jack is handcuffed to the pipe below decks, the elbow joint is a modern welded joint, not a bolted flange joint as in the rest of the ship. I'm sure this was done to allow Jack to move about with greater ease as the water level rose. (Time)

Continuity: Just as Titanic breaks apart, the compass platform (seen in front of the third funnel when the lights were still on) suddenly disappears. The water isn't even high enough to have reached its aft-most legs. The white projection on the deck that held the chandelier in the lounge is also gone, and the ventilator that sits on it is flush with the deck. (Time)

Continuity: Look closely at the location of Rose's beauty-mark the first time you see her at the dock. It is on the opposite side of her face during the rest of the movie. (Time)

Continuity: After being shot at by Cal, Rose and Jack race down the hallways outrunning the rising water. Rose is wearing white sneakers, yet she is seen two minutes later wearing period shoes when Jack retrieves the gate key that the crewman dropped beneath the rising water. (Time)

Factual error: In the scene where Rose demands to be taken down in the elevator to look for Jack, the shadows cast on Rose's face are moving down. Surely if the elevator is moving down, then the shadows cast from outside the elevator would be moving up on Rose's face. (Time)

Other: In the beginning of the film, when Jack is running to the boat on the pier, his rucksack is a Swedish Army rucksack, model 1939, and nowadays widely sold as army surplus. (Time)

Revealing: When Rose is running in the hallways trying to find help for Jack when he is hand-cuffed, she finds a man and asks him to help her free Jack. She gets frustrated with him and says "listen" then hits him. In shots before (you can put it in slow motion to see it) you can look at the man's hand and it already has blood on it before he touches his face. (Time)

Revealing: In the scene where the ship tilts to a vertical position, you see people falling and hitting objects on the deck. In a close up of that, you can see that a black and bronze-topped capstan has wrinkles in it and bends when someone hits it. (Time)

Revealing: When Rose breaks Jack's handcuffs with an axe she doesn't hit the handcuffs on the pipe but Jack's hand. The handcuffs come apart by themselves. (Time)
