Continuity mistake: When Bruce is meeting with Lucius in the office at Wayne Tower, the book on the seat next to Bruce changes positions during their conversation. (00:37:15)
Continuity mistake: During the stock exchange scene, after Bane says "Time to go mobile", the man with the laptop closes the laptop in the background and then does it again in closeup.
Continuity mistake: Catwoman puts her goggles on, shoots the batpod cannons at the car barricade, and in the immediate next shot they are back on the top of her head without her putting them there.
Continuity mistake: The fuselage of the plane is hanging straight down when Bane exits with the doctor, but it should be at an angle to the left, as we see when they are dragged behind the bigger plane.
Continuity mistake: It's a bright sunny day when Bane enters the stock exchange. When the police turn up moments later it's raining, with a wet road and puddles. When Bane exits on the motorbike, the roads are bone dry.
Continuity mistake: When Bruce meets with Lucius in his office his hands change from being on top of his cane in one shot to being just below it in the next.
Continuity mistake: When Selina has Daggett pressed up against a wall, she is shown wearing heels, but later on in the same scene, whilst she and Bruce fighting Bane's mercenaries on the roof, she is wearing flats. (00:52:00 - 00:53:25)
Continuity mistake: The bleachers in the stadium are semi-empty in the aerial angles, but packed with people in the close-ups.
Continuity mistake: When Catwoman is with Bruce Wayne at the charity ball, she has red painted nails. After stealing the Lamborghini Aventador, she is lacking nail varnish, even though she is still wearing her charity ball mask.
Continuity mistake: When Selina is observing the target that Bruce has been firing arrows at, Bruce suddenly shoots an arrow at the target, surprising her. The arrow is shown directly hitting the number 7 on the target. The shot then changes angles and the arrow is now a couple of inches away from the number 7. (00:11:19)
Continuity mistake: During Bane and Batman's first battle Selina is behind Batman when the fight starts, then Bane's back is to her later, but Bane and Batman don't switch positions on the catwalk.
Continuity mistake: During the intro sequence, the camera points upward inside the bottom plane, allowing the viewer to see outside the hole, where nothing apparently exists except blue sky. Cut to an outside shot, and the suggested angle of the plane suggests we should be able to see the top plane outside the hole. Yet whenever we are inside, the top plane and the wires holding the planes together all mysteriously disappear.
Continuity mistake: The scene where Bane overwhelms the guards at the stock exchange and the surveillance tape of that scene that Alfred shows Bruce later are not from from the same take/choreography: In the surveillance tape when Bane shoots the guard with the other guard's pistol still in his hand, in the exact moment the shot goes off (recognizable by Bane's upwards bouncing arm), the guard flails his left arm high and throws his head back as if reacting choreographically to a punch (that punch comes half a second later though). In the original the guard does not flail with his left arm and does not throw his head back the moment the shot goes off. He only does it when Bane actually hits him with his own pistol. Furthermore, you can see from the surveillance tape that Bane's pistol-punch does not connect with the guard's face. (00:42:10 - 00:56:30)
Continuity mistake: When Bruce Wayne and Lucius Fox are discussing the fusion reactor in Fox's office, Wayne's hand keeps switching from being on his cane, to being placed somewhere out of frame.
Continuity mistake: When the girl climbs out of the prison her head gear is not joined under her chin. In the next shot when she covers her head, the bottom is now joined together. (02:12:35)
Continuity mistake: When Batman pulls the bomb from the back of the crashed truck, Gordon and Catwoman get out of the way. Catwoman turns to her right and takes a few steps in that direction, in the next shot she is just stepping backward and has not turned at all.
Continuity mistake: When Catwoman shoots one of the tumblers we see it get hit and explode from behind, then 2 shots later we see her pass from the front. Also after the tumbler gets blown up the next wide shot from above reveals the tumbler is still there.
Continuity mistake: The plane in the beginning has at least 4 rows of seats in the left and 5 rows in the right. In the final shot where Bane and the doctor "slip" out of the plane, the left has only 3 rows and the right one also seems to have no more than 3. Additionally, the last of both rows are level, although in the rest of the scene they are not. Furthermore, Bane and the doctor "start" amidst the seats, although in the last shot they start behind the last row of seats. And the aisle is pretty narrow in the last shot with not enough space to fit an additional seat, compared to the rest of the scene where the gap is wide enough to fit at least two seats. (00:04:10 - 00:06:20)
Continuity mistake: In the aerial shot it shows police cars stopped in front of the moto, but in a shot from the front they've moved several metres further on.
Continuity mistake: As Batman begins to approach Bane during the final battle, be on the look out for a certain extra (a middle-aged man with a grey beard and brown vest). You'll see him fighting behind Batman...only to be seen fighting behind Bane in the very next shot.
Chosen answer: Given that no accurate records would have been kept of what occurred in Gotham during Bane's occupation, it would be very easy to claim that Bruce had been in the city when the bridges fell, been captured and subsequently executed by forcing him out on the ice, as had happened with many other socialites. Plenty of people died during Bane's takeover of the city, particularly in the final hours. There's no reason why Bruce would stand out among them as a candidate, and even if anybody did harbour some suspicion, it could hardly be proven.
