Continuity mistake: Before winning the poker game, right when we meet Jack, his cigarette swaps from worn out and dirty to perfect and spotless. (00:23:10)
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)
Continuity mistake: When Will kills Tommy and commits suicide, the number of dollar bills on the floor next to Tommy's foot change number and position between shots. (02:19:40)
Continuity mistake: When Cal is trying to kill Rose and Jack, then suddenly realises his diamond is in the coat, his fringe swaps from messy to perfect from frame to frame. (02:13:50)
Other mistake: During Rose's attempted suicide as she's hanging off the back of the ship, a horizontal line of dark color is seen below her navel. It appears to be her personal undergarments: modern thong/hip-hugger underwear. (00:39:10)
Visible crew/equipment: When handcuffed Jack tells Rose he's glad she found he wasn't a thief, a boom mike is reflected on the porthole's glass. In wider shots it disappears. (01:55:40)
Visible crew/equipment: When Jack and Rose are running away from Lovejoy (Cal's servant/friend), they run round a corner on E-deck. When the camera follows, the camera's shadow can be seen on the wall. (01:28:45)
Continuity mistake: When the engine room gets the order to cut power to the engines, the wheel that one of the engineers is turning is black, however a few minutes later the wheel is gold. (01:35:00)
Factual error: It's impossible that Rose would've been able to survive for as long as she did whilst wearing that thin, delicate lounging dress she changed into after Jack drew her portrait. She was in and out of the water constantly before finally climbing on top of the door frame in the water, and while the coat Cal put on her could've kept her torso warm, her legs were exposed throughout much of the ordeal. The human body can barely function in freezing temperatures, but she moves around with considerable agility until shortly before she's rescued from the water.
Continuity mistake: When Rose runs to commit suicide, the people she bumps into disappear in the immediate aerial angle. (00:35:10)
Factual error: A point is made in the movie, and it is well known, that the water temperature of the ocean where the Titanic sank is near freezing, and at the end after it sinks, the people in the water only last a few minutes before going into an unconscious stupor and then dying. but on the boat, as it is taking on water while it is sinking, Jack and Rose are running around in this freezing water for what seems about 30 minutes with no apparent ill effects. The water could not have been heated substantially, and they simply could not have lasted nearly as long as they did running around in this water as the movie showed without slipping into unconsciousness. (02:38:30)
Suggested correction: In movie time it is only a few minutes that pass yes, but realistically nobody really knows how long they were in the water before they all started dying. It could have jumped to 30 minutes later when it is quiet. Also, Jack and Rose on the boat were not submerged in water for 30 minutes consecutively, but rather in and our of water and only up to their necks for a few seconds at a time.
Audio problem: When the one lookout says "b*****ks", his mouth doesn't match what he is saying. (01:31:20)
Continuity mistake: After Rose refuses to get in the lifeboats there's a shot of handcuffed Jack crying for help. A frame later his fringe has swapped from combed to parted. (01:52:40)
Factual error: In the famous "I'm flying" Scene, the sunset is to the couple's left. But at that time (April 14) the ship was definitely steaming due West, and the sunset should therefore have been directly in front (or even a bit front-right). (01:17:00)
Continuity mistake: When Rose finds Jack handcuffed, the papers by the corner of the table next to him swap from being white coloured to yellow, plus being on the very edge or not, depending on which angle is shown. (01:55:40)
Factual error: When Cal overturns Rose's table, there is a serving cart with modern-day casters. (01:08:10)
Continuity mistake: When the Captain tells the morse operator to make an emergency call, the position of the papers and pencils in front of him move around between shots. (01:44:50)
Factual error: When Jack goes up to first class on a Sunday morning, the group is singing the Navy Hymn "Eternal Father." What is impossible is that they are singing the verse written for Aviators. The verse starts "O Spirit, whom the Father sent." They are singing the whole stanza continuing with "to spread abroad the firmament; O Wind of heaven, by thy might; Save all who dare the eagle's flight, And keep them by thy watchful care." The last line "From every peril in the air" can only be heard in the background as Jack is arriving on the scene. The Wright Brothers flew about 8 years before, and this verse was not added until the late 1930s. (01:11:00)
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)
Factual error: Rose turned left after exiting the elevator during the search for Jack during the sinking. In the real Titanic, there was a wall to the left of the elevator in E Deck. In addition, going left from the elevators would take her to the port side of the ship, but the corridor outside the cabin where Jack is is on the starboard side. (01:53:40)
Suggested correction: Coming out of the elevator, you turned left to have access to the long corridor called Scotland Road.
