Continuity mistake: When Jack and Rose have first met and are talking and walking on the promenade of the ship, in a wide shot of them, to the left of the screen stands a man with a hat in his hand talking to a lady. In the following shot his hat is on his head. (00:45:50)
Continuity mistake: 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. (00:46:15 - 00:49:10)
Continuity mistake: 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. (00:46:30)
Continuity mistake: When Jack and Rose are talking on the deck. Rose is explaining to Jack why she considered jumping. She stated that she felt that she was screaming at the top of her lungs and no one was listening. He looks at her ring and states that she'd sink straight to the bottom...yadda, yadda, yadda. If you watch that scene, pay attention to Rose's hair. One second her hair is perfectly curled with bangs, then it is behind her ears. It alternates back and forth: bangs, no bangs, bangs, no bangs until she grabs his portfolio and they sit down on the chairs to look at his drawings. (00:47:20)
Audio problem: After Jack asks Rose "do you love the guy or not?" the camera shows him from behind, and he is moving his jaw as if he is asking the question again. (00:47:30)
Continuity mistake: When Rose is looking through Jack's sketchbook when they are sitting on deck near the beginning of the movie, Rose's hair changes form shot to shot. From one angle it is very messy, with a lot of wind blowing it around. However, from the other angle her hair is perfectly styled into ringlets around the front, with little or no wind blowing at it. (00:48:40)
Factual error: When DiCaprio is showing off his sketchbook, there is one with a man's hands around a young girl's torso with his hands on hers. This drawing is an exact replica of a photograph by celebrated photographer Sally Mann called "Rodney Plogger at 6:01, 1989." Most likely a tribute of some sort by the director to a fellow artist, but obviously this drawing is out of place in 1912. [From the New York Times Arts and Leisure section, Sunday, November 19, 2000: "The film director James Cameron copied an image from "Immediate Family" and displayed it prominently in "Titanic" without Ms. Mann's permission. The resulting grievance was settled out of court for a substantial sum just weeks before the Academy Awards."] (00:48:45)
Revealing mistake: If you look at the deck planks to the right of Rose and Jack you can see that there is something that runs perpendicular to the rest of the planks. This wasn't on the real Titanic. This is where the set was "cut" so that the front half could be sunk into the tank later on in the film. (00:51:00)
Factual error: In the scene just before the spitting lesson when Rose and Jack are strolling on the deck, you can see Pacific ocean shore waves breaking towards the ship. (00:51:45)
Continuity mistake: In the scene on deck where Jack is teaching Rose to spit, for a split second you can see the breakers rolling in to shore through the ship's railing. Also in this scene, the angle of the shadows changes constantly, indicating the scene was shot several times throughout the afternoon and then spliced together. (00:52:00)
Continuity mistake: When Jack is teaching Rose how to spit, then gets caught by some ladies, he has a glob of spit on the far upper right side of his chin, then the shot switches and it is now on bottom middle and a little to the left of his chin. (00:52:25)
Factual error: When Jack describes taking Rose to the Santa Monica Pier, he specifically mentions riding on the roller coaster. Although the pier itself did open in 1909, the land for the amusement portion of the pier was not even purchased until 1916. (00:53:45)
Visible crew/equipment: When Jack comes to the first class door for the first time in his tux, you can see a cameraman in the glass door just before he enters. (00:54:55)
Continuity mistake: When Jack is waiting for Rose at the staircase (before dinner) he is mimicking the hand gestures of an older gentleman. As Cal and Ruth walk down the stairs, we see a shot of Jack from behind, and his arms are at his sides. In the next shot when Cal goes to greet the Countess, Jacks posture is back to the mimicking of the older gentleman. (00:55:40)
Continuity mistake: When 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. (00:57:15)
Continuity mistake: When Rose is introducing Jack to the first class passengers, they (Jack, Rose and Molly) start walking towards the dining area. Cal turns around, and says "Sweet Pea", obviously calling for Rose. When it does this, you can see Rose, Jack and Molly facing another direction, still talking to J.J Astor. Next shot, they're facing Cal again, on their way to dinner. (00:57:45)
Continuity mistake: Right before dinner, Jack and Rose are talking to the Astors, and Molly comes up from behind them, asking Jack to escort her to dinner as well. In the next shot, when Cal calls back to Rose, Molly is still walking up to them. (00:58:15)
Continuity mistake: In the dinner scene, just after Jack says, "Never did like it much", Cal starts laughing, but in the next shot he has a straight face and is chewing. (01:00:00)
Continuity mistake: When Jack is dining in first class with Cal Rose and the others, when the men get up to leave, and in one shot you see Cal walk past Jack, and in the following shot he is walking past again. (01:02:15)
Continuity mistake: When Jack is asking Rose to dance after dancing with the little girl "Cora", you will notice that Jack's hair is down when first asking her and when the camera goes to Rose and then back to Jack that it is back up with, all nice and neat. (01:04:35)
