Continuity mistake: When Rose enters the cabin where Jack is handcuffed, the pillow on the berth behind appears/disappears between shots. The black jacket on the desk and items on the shelf also disappear. (01:55:40)
Continuity mistake: When Jack and Cal finally convince Rose to get on the lifeboat, Jack's hair is very scruffy with slight curls at the tips. When Rose jumps back on the ship, and Jack runs back inside to meet Rose again, his hair is perfectly straight and very well conditioned. (02:13:50)
Continuity mistake: When the windows are breaking in the grand staircase the first two next to the piano break at the same time. But then a few seconds later the second window is breaking again. Another mistake is that the piano went from the port, to the starboard side suddenly. (02:35:15)
Continuity mistake: In the beginning, when the safe is being opened, there's a close-up of the grinding wheel digging into the metal. In the next shot the crewman who does the job is only kneeling down, while the grinding sound is already there. (00:09:00)
Continuity mistake: Rose walks through the chest-deep water with the axe, holding it vertically when seen from behind and horizontally when seen from the front. (02:03:25)
Continuity mistake: When Rose slips during her suicide attempt and Jack grabs her right hand there's a shot from behind where her left hand is holding on to the second railing bar from the bottom. When the camera angle changes she is holding on to the bottom bar, and in the next shot again to the second. It's unimaginable that she would change her grip that frequently in this situation. (00:40:55)
Continuity mistake: When 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. (02:50:00)
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: In the scenes depicting the shift of materials onboard the ship during the wreck, the same china, from the same shelves, fall twice. (02:33:15)
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)
Continuity mistake: When 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. (00:31:40)
Continuity mistake: When Rose and Jack run outside after making love in the car, you will notice a shot of the men in the lookout tower where you can see their breath due to the extremely cold night. But when the shot goes to Jack and Rose, you will notice that you cannot see their breath but also Rose does not seem to be affected by the cold even though she is wearing a thin dress with no sleeves. (01:33:35)
Continuity mistake: 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. (00:35:55)
Continuity mistake: 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. (00:27:45)
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)
Continuity mistake: 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. (02:12:50)
Continuity mistake: When Rose, Cal and the others sit around a table talking and drinking, and Mr Ismay says something. His hands are locked together by his fingers, but in the following wide shot his left hand is down by his knee and his right is holding a fork with food on it. Also, Rose puts the cigarette holder to her mouth and takes her left hand away from it but in the following shot her left hand is still on it. (00:32:30)
Continuity mistake: Right after the 1st smokestack has fallen and crushed Fabrizio, it is seen from above creating huge sprays of water. The problem is that the smokestack looks nothing like the Titanic's. You can see the top and there is no black whatsoever. And to make it stranger, there is a cable attached to it and then one below it, both on the peach/orange color, and not the black. (02:36:10)
Continuity mistake: When Rose attempts suicide she is holding onto the railing while standing on the outside. In some shots the black lace from her dress is held under her left hand, in some it isn't. (00:37:40)
Continuity mistake: 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). (01:18:40 - 01:21:20)
