Corrected entry: During the bank scene, there's 5 guys. Three in the car, two on the roof. As they begin the robbery, there are three on the bank floor, one in the vault, two on the roof (where did the extra guy come from?) The guy on the roof deactivates the alarm, gets shot. The shooter then goes down to the vault, where he shoots the vault guy. Technically leaving us with 4 guys still in the bank. He then begins to collect the money in duffel bags. While this is happening, the bank manager shoots and kills one robber, shooting him in the back. Leaving two robbers on the bank floor and one in the vault. Manager shoots the second robber in the arm, "where you learn to count?" Joker shoots manager, and begins loading the duffel bags. The only problem is the the vault guy never came up. He never bought the money to the floor. Joker shoots the last robber, shoots the bus driver and leaves. What happened to the money guy and where did the vault guy come from? "Three in the car, two on the roof."
Corrected entry: A minor quibble, but it would be near suicide to ride a motorcycle wearing a six-foot cape. The drive assembly and or rear wheel/axle would eventually grab it and snap your neck.
Corrected entry: When the Joker, Grumpy and Chuckles get out of their station wagon and rush into the bank, you can see that they are parked on the south side of Van Buren Street and their car is facing east, just west of the drawbridge over the river (as indicated by 301 South Wacker Drive being visible in the background). They then enter through doors at the east end of the lobby. When the Joker is starting up the bus and pulling out of the bank's west lobby doors, the entrance suddenly changes to being on the north side at the west end, as he only makes a 90 degree right turn to join in with the other buses, which are driving east on Van Buren Street. He should actually have to make a full 180 degree clockwise turn through the intersection of Canal Street and Van Buren. (00:02:05 - 00:07:00)
Corrected entry: In the scene where Joker is doing the "magic trick" with the pencil, he first stabs the pencil through the table, and we can see that he stabbed it because it is leaning to the side and the metal band is at the top. After he slams the guy's head down onto the pencil, there is no hole in the table.
Corrected entry: When the batman goes into attack mode in his tumbler on the Lower Fifth chase, he shifts in the right side of the cockpit. But when he ejects the batpod he appears to have comes out from the left side of the cockpit.
Corrected entry: The events of this film take place immediately after the events of 'Batman Begins'. In the previous film, Lucius Fox introduces and describes the 'Tumbler' to Bruce Wayne as a military prototype 'bridging vehicle', designed to jump across ravines and chasms to drag lines which would then be used to pull bridges across. The vehicle is then used in that film is ways that are consistent with the expected features of such a vehicle. However, in this film the Tumbler (now officially the 'Batmobile') suddenly acquires the ability to shed its outer skin, revealing the motorcycle-like vehicle from within. Not only does this serve no conceivable purpose for an intended 'bridging vehicle', but that ability would preclude the interior passenger space shown quite thoroughly in the previous film. Also, there has not been any time between the two films' timelines in which to make the modifications necessary for such a feature, even if they only recently decided to add it.
Corrected entry: During the big finale in the unfinished skyscraper, Batman discovers that the clowns are really the hostages. Why doesn't he contact Gordon and let him know right away? Batman was just in contact with Gordon on his way there (his batsuit is obviously equipped with a headset). Gordon could easily have alerted the SWAT team, and Batman would not have had to go through the trouble of methodically bringing down all the SWAT team members so they didn't fire on the hostages.
Corrected entry: When Reese unfolds the blueprints of the 'Tumbler' and puts them on Fox's desk, the drawing of the right-hand side of the vehicle is incorrectly labelled 'Left Elevation'.
Corrected entry: During the opening bank robbery, after the robbers fire a few rounds into the air to get the attention of the customers and tellers, one robber, Chuckles, grabs one of the guards, drags him over to the desk, and pistol whips him over the back. Seconds later, right before Chuckles is killed by the shotgun-wielding bank manager, the same pistol-whipping moment is repeated as a close-up.
