Factual error: During the drawing scene, 'Jack' is using modern square sided, pressed charcoal with numbers embossed in the side of it. In 1912, Jack would have been using vine charcoal which was round and made of 'charcoalized' willow twigs.

Continuity: 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.

Continuity: The length of Rose's fingernails changes noticeably throughout the film. In some scenes, her nails are very short (during the "flying" scene), and in other scenes her nails are a lot longer (when she takes the comb out of her hair right before Jack sketches her).

Continuity: After Rose has been persuaded to step into the lifeboat the camera is on Cal and Jack for quite some time when Cal reveals to Jack that there is no arrangement in his benefit. During all this time the lifeboat is being lowered, but when the camera cuts back to Rose she can still make eye contact with Jack almost at level.

Continuity: Early into Rose's suicide attempt scene Jack's hair tucks itself behind his ears while his hands are in his pockets.

Continuity: In the scene where 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.

Continuity: Right after the lights go out there is a structure directly aft of where the ship will break that on both sides of an angled roof have four panels, each with four portholes (a skylight). After the ship has broken apart and the smokestacks are falling off, it is now open.

Continuity: In the scene where the lifeboat is passing and Rose is trying to wake Jack, Rose's hair shifts from shot to shot. In some, there is some hair hanging in front of her face, but from the side that strand disappears. It once again reappears as she shifts before rolling into the water.

Continuity: When Rose has just boarded titanic and is looking through her "finger" paintings, she is holding a painting, then slides it down her fingers. When she slides it down, she slides it almost to the end of the painting's frame, but in the following shot she isn't even close to the edge/end of the painting.

Deliberate "mistake": When the ship is leaving Southhampton, there is an underwater shot of all three propellers starting to rotate together. This is incorrect as the middle turbine engine ran of the waste low pressure steam from the outer wing reciprocating engines, thus the outer engines would have to be running for some time before steam was fed to the turbine. The turbine was only used when getting the ship up to full speed, not maneuvering in ports. Also the three props started revolving at 60-70 revolutions per minute, this was a speed that would have given the ship 19 - 21 knots and the ship would have been wrecked in The Solent/Southampton waters if she was lucky with no loss of life.

Revealing: In the scene where Rose is looking at Jack on the bow of the ship, you can see a tiny bit of desert behind him.

Continuity: In the scenes depicting the shift of materials onboard the ship during the wreck, the same china, from the same shelves, fall twice.

Continuity: In the scene where Jack is howling at the front of the ship, he puts his arms up. His left arm is behind the rope, but in the next shot of him, his arm is in front of it. In the next shot, it is behind again.

Factual error: Among the items recovered from the ship is an old hand mirror. While suspension of disbelief allows us to accept that a mirror could last this long intact, the fact is that submerged in water, at that pressure the mirror would have turned streaked if not turned totally black.

Continuity: When Jack rescues Rose from her suicide attempt she slips. In the shot from behind when she is seen dangling precariously her (or the stuntwoman's) hair is longer and redder. Kate's stunt double is noticeable in other shots throughout the film.

Continuity: When Rose is running to get to the stern to throw herself off she starts by running on the first class A-Deck promenade. Then when the whole stern of the Titanic is shown sailing, Rose runs out from the 2nd class B-Deck promenade, a deck down. The only way that these two promenades were connected was by two ladders, which Rose passes when she keeps running. It makes no sense to go down the ladders, go forward, turn around and head back to the aft part of the ship.

Continuity: During a scene where the ship is sinking, Jack and Rose are seen in front of a roaring fire. The coal or logs on this fire do not roll off despite the acute angle of the ship. A clock, glass and ornaments on the mantlepiece above the fire do not slide off and if you look closely at the half filled wine glass on the mantle, the wine is completely level despite the room tilting further and further.

Revealing: In the suicide attempt scene, after Rose climbs over the railing, you'll notice banding of the night sky a couple of times - that appears on both VCR and DVD.

Continuity: The steel deck fittings at the bow of the ship change shape. During the flying sequence, the fitting nearest Rose's right foot changes from a curvy shape to a flat angled shape.

Continuity: In the scene where Hockley and Lovejoy find the drawing of Rose in the safe, Hockley is holding the drawing which has been secured in some kind of brown manila folder. A split second later, Hockley reads the note Rose left while still holding the drawing (and even angrily squishing it slightly with his hand), and it is not in a manila folder.
