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)
Continuity mistake: When Jack and Rose are dancing on the 3rd class level, Rose takes her shoes off and looks down at her feet, in the following shot she is looking at Jack, and the shot after she looks at Jack again. (01:05:30)
Continuity mistake: When Jack gets 2 pints in the 3rd class party, he hands one to Rose. Who then drinks it. When Rose is given the pint, there is a decent head on it. Camera cuts to her drinking and there is no head at all. (01:06:20)
Continuity mistake: In the scene where Jack and Rose are on the third class level partying with the other people in third class. When Jack hands Rose a glass of beer, how she holds the glass differs between shots. (01:06:20)
Continuity mistake: As Rose shows the men she can rise up on her toes, from the front she has a cigarette in the first three fingers of her right hand.

Continuity mistake: When Jack is sneaking over the rail to the first class deck, a boy is preparing to spin his toy top. As Jack leaps the rail and begins walking, the boy throws the top and you see it start to spin. The camera angle then changes to show Jack walking, toward the coat he is about to 'borrow', and in the background you can see the boy again drawing back to toss his toy top. Since you have to meticulously wind the string around the top of the toy, it would be impossible for him to be making a separate toss. It's obviously the same toss filmed from two separate angles. (01:13:40)
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)
Continuity mistake: When Jack holds the diamond his nails are clean and perfect. When he starts to draw they are ugly cut and dirty, revealing they're somebody else's hands (later known to be director James Cameron's). (01:21:00 - 01:23:30)
Continuity mistake: When Jack is about to start drawing Rose, the shot cuts back and forth from a close-up to a wider shot. In the wide shots Jack is holding his charcoal pencil, in the close-ups he is not holding it. (01:23:10)
Continuity mistake: 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. (01:23:15)
Continuity mistake: When Jack is drawing Rose, the first close-up of Jack's hand shows charcoal on his thumb and nail which vanishes seconds later on the next close-up. (01:23:30)
Continuity mistake: When Jack is preparing to draw Rose, when he says "Try to stay still", on Jack's sketchbook we can see some sort of bookmark or flap. Right before he starts drawing, when he exhales, that little flap thing is missing. (01:26:35)
Continuity mistake: When Jack and Rose are running from Lovejoy, they stop for a moment on E deck. When they do, look behind them and a member of the ship's crew comes into shot holding a bag of something. When Jack and Rose start running again, this man has disappeared. (01:28:20)
Continuity mistake: Inside the car, Jack places his hand on Rose's shoulder, but a frame later it's on her arm. (01:30:00)
Continuity mistake: Inside the car, Jack asks Rose "Nervous?" and she turns her seriousness into a big smile. Just a frame later, from the opposite angle, she is still very serious. (01:30:10)
Continuity mistake: After the sex scene between Rose and Jack, Rose's hair is wet with sweat. When the two of them appear on deck, her hair is exactly as it was before the sex scene. (01:30:40)
Chosen answer: Because she is considered, in a minor sense, a "villain" in this film for forcing her daughter into a loveless arranged marriage to satisfy her personal wants, most fans probably speculate that she became a poor and penniless seamstress and lived out her life working in a factory. Of course, this is possible, without the financial security of the arranged marriage between Cal and Rose. However, it is difficult to believe that a woman of such status, and who has so many wealthy and powerful friends, would be allowed to languish in abject poverty doing menial labors. I would tend to believe that she probably sold a number of her possessions for money (she did mention that as part of the humiliation she would face if Rose were to refuse Cal's affections), and probably lived off the kindness of others. Given that her daughter was betrothed to a Hockley, his family might have felt an obligation to assist her in finding a suitable living arrangement and a situation for employment. It is also possible that she re-married into wealth. However, this is more unlikely, mainly because back in 1912, it was considered scandalous to re-marry, especially at Ruth's age. However, since Ruth does not make an appearance after surviving the sinking of the Titanic in a lifeboat number 6 (next to Molly Brown), nor is she mentioned again, her fate is left unknown and subject only to speculation.

In that era, with Rose betrothed to Call, Cal would most definitely have provided for Ruth in the lifestyle she was accustomed to. As Cal angrily raged at Rose the morning after her excursion below decks, "You are my wife in custom if not yet in practice ", thus, society would have viewed him a villain had he not cared for Ruth once it was assumed Rose was dead.
