Continuity mistake: 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. (02:25:35)
Factual error: On the real Titanic the first set of davits were cranked back in to lower the lifeboat Cal is in, not the second set. One of the davits that should have been cranked back in is still on the real Titanic in the position ready for picking up the lifeboat to lower it. (02:25:40 - 02:34:45)
Continuity mistake: When Officer Murdoch looks down the stairway from boat deck to see A deck flooding below, the stairway video is reversed. The railing is on his left (looking down stairs) and the water is coming in the left side. This is wrong as shown by previous scene of man climbing stairs with railing on right, later by overhead video of stairway, and by ship plans. (02:25:55 - 02:27:30)
Continuity mistake: Close to the end of the film when lots of people are trying to free the lifeboats from the ropes, you can see Cal, climb up a black wire and stand on the side of a half turned lifeboat, but if you watch closely in the following shot, you can see that Cal is still climbing up the black wire. (02:27:55)
Continuity mistake: Rose is wearing low heeled laced shoes throughout the entirety of the sinking scenes. Jack helps her jump off a small deck in order to flee for the lifeboats (she's wearing her lifejacket at this point). In this scene, Rose is suddenly wearing flat moccasin-type shoes of similar bone colour. Shoes then revert back to low heeled lace-ups after small jump assisted by Jack takes place. (02:28:30)
Continuity mistake: When Jack and Rose are on the way to the end of the ship to try and stay on as long as possible, you can see them jump down from a railing, but if you watch when Rose jumps down, a woman also jumps down next to her and falls over, yet in the following shot she has vanished, then in the background she can be seen jumping down again. (02:28:55)
Audio problem: When the Captain is watching the overturned boat trying to be launched, there is a crew member working on the davit, causing it to make a rapid clicking noise. But soon after the noise stops, the crewmember is still turning. (02:29:15)
Continuity mistake: When the pastor is giving a sermon on the deck of the sinking Titanic, there are people grabbing his hands in one shot and not in the next. (02:29:45)
Continuity mistake: When the funnel tips over it breaks at the bottom. The camera cuts to Cal, then back to the funnel, and it breaks again. (02:30:00)
Revealing mistake: Towards the end of the film when Titanic is gradually getting higher Rose and Jack finally make it to the top of the ship, watch closely at the shot when they approach the top of the ship and Rose grabs onto Jack. In the background right at the very top of the shot you can see many green screens stood at the top of the ship in the background where people are running around. (02:30:00)

Continuity mistake: We see the plates sliding out of the holder and smashing as the ship starts to go vertical. Then 50 seconds later we see more plates falling from the same holder. However, the positions of the plates have changed and there are stacks of plates in sections that were empty. (02:30:10 - 02:31:00)
Continuity mistake: When Rose and Jack are on the back of the sinking ship, when she looks to her left at the woman next to her, she has almost no makeup on, but when she turns her head back to Jack, she has fresh makeup on. (02:30:30)
Revealing mistake: In one of the sinking scenes, you can see the rectangular strobe lamps showing through the black fabric in the glass dome. (02:30:35)
Continuity mistake: When Jack and Rose are on the way up to the end of the ship, they go past a priest with lots of people praying, some are holding his hands, yet in the following shot, the people are not holding his hands, and are a bit further away from him than in the previous shot. (02:31:20)
Factual error: The Strauses (the old couple on the bed as "Nearer My God to Thee" is playing) had stateroom C55-7 on C-Deck, right off the grand staircase. When the ship is sinking there is water coming in from the door in their cabin. But Rose's artwork is seen floating on top of the water a few seconds later. Her cabin was B52-56 (also just aft of the grand staircase) on B-Deck which was above C-Deck. So the Straus' cabin would have been completely flooded. (02:31:20)
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)
Factual error: When the stern (back) of the Titanic is rising into the air, there is one shot where it appears bone dry. Easily hundreds of gallons of water would have been pouring off the still wet hull. (02:34:10)
Continuity mistake: When the ship begins to tear apart and the inside is seen collapsing, the room shown is a combination of the lounge's windows (already submerged as shown by the floating girl) and the smoking room's ceiling. Also according to where the ship breaks in the movie these rooms are not part of the tear. (02:34:50)
Continuity mistake: During the break-up of the ship, David Warner's character, Lovejoy, is right where the gash starts. Right after we see the interior break-up shot, we see the hull breaking, and on the top, where Lovejoy should be, he is nowhere to be seen. (02:35:00)
Revealing mistake: In this scene, at the end of the film when Jack and Rose are hanging onto the railing, you can see the ship split in half, but when it drops, if you watch closely on the right side of the screen, you can see that the entire ship is still intact, the lifeboat cranes are visible all the way down the top of the ship. (02:35:10)
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.
