Other mistake: When Alice asks Dan to make her some tea (after he tells her about him and Anna), he walks into the kitchen for just a moment, and comes back to find her gone. He also doesn't see her as he runs downstairs and looks outside. She couldn't have quietly gone down the stairs and out of the building in the short moment that Dan was in the kitchen. If she had moved quickly, there should have been a lot noise from her footsteps.
Other mistake: When Stevo cries as he discovers Heroin Bob dead, you can see Bob breathing.
Other mistake: When De Niro and Bridget Fonda are talking and trading hits off of bong, alone in the apartment, while they're talking there comes a pause where they both look at each other with their mouths closed, and you can here someone coughing in the background.
Other mistake: When the firefighter is fighting with the arsonist, the gas line is disconnected from the fireplace. Just before the dramatic explosion, the gas line ignites. This is incorrect because the fire would have started from the outlet to the gas (from ignition source to fuel source).
Other mistake: In the scenes after Giovanni Ribisi is arrested, his looks are constantly changing. In scenes where he is talking to Vin Disel his face is very fat. When he walks by Abby's desk he is thin again. If you get Boiler Room on DVD you'll see an original ending where Ribisi is thin all the way through the end of the movie; Because Giovanni was preparing for a film that required him to gain 30 something pounds, the scenes that needed to be reshot for a different ending are very defined.
Other mistake: When Don and his father are driving home and Don's father throws his ring out the window, Don gets out to search for the ring and you can see wet marks on his shins from kneeling on the wet road. However, he hasn't knelt down yet. It must have been from previous takes. Also, when he gets up after kneeling down, his jeans are dry. (01:01:50)
Other mistake: In one of the beginning scenes, when Noah and Fin are at the fair, you see Allie and Sarah on the bumper cars. Allie bumps into Sarah, and you can see and hear Sarah yell "Rachel," which is actually the name of the actress who plays Allie - Rachel McAdams. (00:05:20)
Other mistake: When the Pirates are arrested in Nineveh, another soldier walks up to Jonah and knocks him out with a fish. When this happens, Jonah is wearing the Cheese Curl hat. When he comes to on the Slap of No Return, he is wearing his turban again. Would the soldiers change his hat?
Other mistake: In the scene where Cameron is sinking in the pool you can clearly see some kind of weight belt or something around his waist, which isn't there when he is out of the pool.
Other mistake: After the one bad guy crashes into the giant vat of toxic waste, hardly any of the liquid from the container spills out for the first two shots. Then a few cuts later, almost all of it pours from the back of the truck. Judging by the size of the hole it left, more liquid should have been coming out around the truck, not just through it. (01:29:00)
Other mistake: When Jack draws Rose the hand that is shown in close-up is much too old to be his. [It's James Cameron's hand - still a mistake, but there's why.] (01:23:40)
Other mistake: When at sea and during the crew member foc'sle rescue, the ship's crew, including Kevin Costner, are wearing ship ball caps reflecting USS Billings (BB 1369) and the BB represents "Battleship." However they are actually on a Guided Missile Destroyer "DDG 21", the USS Cochrane, as indicated by the hull number 21. (00:15:00 - 00:17:00)
Other mistake: At the end of the movie where they are looking at the headstone of Jake Hobart, the date on the bottom of the stone is April 3 1913, despite dying shortly before the Titanic sank in 1912.
Other mistake: When Travis is negotiating with Sport for Iris' services, an off-screen crew member can be heard saying, "but no rough stuff" just before Sport says it. (01:17:00)
Other mistake: In one of the opening scenes where the boys ride to the baseball game, the fishermen they pass make a rude comment towards them. In response, you hear Joe ring his bicycle bell and see them flip the men off. The bicycle has no bell.
Other mistake: When the main characters are in the motel and they hear the moth flying outside the window, Stu, the creepy deputy with the glasses, picks up a shot gun and racks a round into the chamber. In the next shot of all of people firing at the moth through the window, Stu is now holding his revolver and fires with it. When he runs of out ammo with the revolver he picks up the shotgun again and before firing racks the pump again. Since he already did that the gun should have ejected the unfired shell that was already in the chamber from earlier, but no shell is ejected.
Other mistake: During the jury selection montage the judge says 'Enter Lydia Deets as a juror.' Moments later, her profile is shown on screen and the lawyers accept her and the judge says 'Enter Miss Deets as a juror.' she has been entered into the list twice.
Other mistake: While asking Napoleon to pull him into town, Kip is putting on his roller blades. They live on a gravel road seen in other shots which would be impossible to rollerblade on while being towed behind a bike.
Other mistake: Capt Cahill was declared dead after the helicopter he was in crashed and then taken captive. I spent almost 24 years in the military and know that if a body is not found, even though presumed dead, the official status is Missing in Action (MIA). The notification to Capt Cahill's family should have been MIA not dead.
Other mistake: When Philomena and the journalist are waiting to board a return flight from Washington to London, he calls his office in London where a clock shows it is 8:55. That would make it 3:55 in D.C. It can't be 3:55 pm because it is dark; so it has to be 3:55 am. And no flights leave for London until 3 or 4 hours later.
