Continuity mistake: During the bank robbery, when Joker takes off his mask, before the camera changes angles, he uses his right hand to remove the mask and his left hand is holding up the manager's head. When it cuts to a front view, he is using his left hand to remove the mask, but when it cuts back to the first angle Joker's left hand is supporting the manager's head again. (00:05:30)
Continuity mistake: In the scene where Joker is visiting Harvey in the hospital, there is a shot of Harvey's face just before Joker takes his hand, and there is a tear on Harvey's cheek. However, in the next shot of Harvey's face, the tear is gone, and there is no trail where the tear would have fallen, and Harvey's hands don't go to his face.
Continuity mistake: In the opening heist scene, a clown grabs a bald bank teller. In the wide shot, the blonde bank teller to the clown's left reacts in fear. However in the very next shot, she is motionless and reacts again in fear. (00:02:45)
Continuity mistake: When Dent is talking in the hospital after being rescued, the pillow is bloody on his left side (where he was burned) then the pillow is clean again in another shot.
Continuity mistake: In one of the first scenes with Det. Ramirez, you see her holding a cup of coffee. She switches between holding the cup with two hands, then one hand and finally two hands again. The cuts in the scene are immediate and linear, so she could not have changed how she holds the cup in between cuts.
Continuity mistake: In the opening shot, there is a long shadow over the roof of the bank building as the camera zooms over and towards the windows in the far building. In the next shots, the shadow is gone as the robbers glide across and land on the roof. (00:01:20)
Continuity mistake: When Batman is about to glide into Lau's building they show him standing on the ledge about two meters from the corner, ready to make his jump. Cut camera angle to an overhead shot and he is standing on the corner of the building when he makes his jump.
Continuity mistake: In the car chase, as they exit onto lower 5th, the convoy has, in order, a police cruiser, 2 swat vans, then 2 cruisers. When the garbage truck pulls up next to the convoy, he takes out the second to last cruiser first (there is a car visible behind). It then spins out another cruiser in front of it before reaching the van with Dent in it, but there should have been no other cruiser between that one and the van. (01:13:00)
Continuity mistake: When the Joker is taken to Gambol, he shoots a pool ball. We hear it connect with another ball, and then five seconds later the ball reappears. When it reappears it is moving too fast to have taken the time it did. (00:28:30)
Continuity mistake: Just after Gordon gets a call from Batman saying, "Gordon, I have the Joker's location, Pruitt building" it cuts to an aerial shot of the building. On the building there is a construction banner with the logo DAVIS, with a blue anchor shape logo. Then later on, when Gordon has the binoculars and says, "Why would they choose a spot with such good weakness" there is another aerial shot where the building banner now read BOVIS, with a blue arch logo. (01:56:55 - 01:58:55)
Continuity mistake: When Joker is looking for Harvey, he grabs Rachael and holds her head. Camera cuts and his grip on her head/face changed instantly. (00:49:25)
Continuity mistake: When Harvey is talking to the fake cop, he hold a coin and says, "Heads, you keep yours, tails, not so lucky." When he says this, the way he holds the coin changes instantly. (01:04:10)
Continuity mistake: In the scene when the Joker talks to Harvey in the hospital, Dent's head changes position from the left side of the pillow to the right.
Continuity mistake: When Batman is removing the part of the wall with the bullet in it, we see the bullet hole is off-center, to the left side of the block that Batman carves out. In the next scene where we see the mounted gun shooting specialized bullets into blocks, Bruce compares the block he removed from the apartment, which is in a plastic bag, to the holes left in the sample blocks. The hole in the block from the apartment is now in the center of the block, not on the left side as it was when he removed it.
Continuity mistake: When the Joker first opens fire on the prison van, you can see that his pistol locks open as if it were empty. However, if you look closely, you can see the empty shell is stuck between the slide and the chamber. In the next shot, he keeps on firing like nothing ever happened.
Continuity mistake: During the scene where Alfred tends to Bruce's bite wounds, the angle cuts several times between Alfred and Bruce. When the camera is on Alfred, Bruce is mostly looking down towards the wound. When the camera is on Bruce, he looks straight at the camera. (00:12:25)
Continuity mistake: When Batman throws the Joker over himself and off of the building he catches him with his rope gun, in the first shot two cables are shown holding him up and in the next there is only one.
Continuity mistake: As Batman appears in the bank vault, Ramirez looks to Gordon. The scene cuts to Gordon, who acknowledges her to leave the vault. When the scene cuts back again she is already a few meters behind Batman. There's not enough time for her to cover the distance. (00:10:15)
Continuity mistake: In the interrogation scene just before Batman slams the Joker's head into the table, it can be observed that the Joker's nails are somewhat long. However, as the scene escalates to where the Joker's back is against the wall and he's clutching Batman's forearms, the Joker's nails are short.
Continuity mistake: In the scene where Batman is interrogating the Joker at the police station, Jokers make-up smears and is rubbed off when he rubs his forehead (after Batman slammed it into the table). Batman later in the same scene strikes the Joker in the face. He should have some make-up on his gloves left, yet does not.
Answer: The gun fires using compressed carbon dioxide as a propellant. The cable is wrapped in a coil around a motorized turbine within the gun. The pulley system in Batman's belt buckle allows him to reel himself in hands-free and still maintain equilibrium. There is a four-pronged grapple at the end of the cable. This is what is magnetized, creating an attraction between it and the monofilament cable. This ensures that the grapple will attach itself to the cable for a secure hold. This is why the magnet itself does not need to be especially strong to support any amount of weight. It also explains the relative ease with which it can be detached and its seemingly "magical" ability to wrap itself around various objects.
