Factual error: The bat signal at the end of the film defies physics. The spotlight is a few feet across and is projecting the signal onto clouds far above. To do this, the light beam should get wider as it climbs up (like a flashlight's beam aimed at the ceiling). Yet the shot of the clouds shows rays of light getting wider as they go downward, like sun rays through the clouds. For this to exist, there's either a bat signal floating far above and through the clouds, or the one on the roof needs to be several miles wide, focusing a beam that narrows as it climbs.

Continuity: When the Tumbler leaps toward the steeply-angled rooftop (the shingled roof with dormers), beyond it is a tall office building on the opposite side of a highway that is running perpendicular to the Tumbler's direction of travel (and parallel to the face of the office building). In order to leap onto this highway, the Tumbler will need to make a hard left or right turn, as going straight will take it across the highway into the face of the office building. But as the Tumbler reaches the end of the angled roof, suddenly the office building has moved far to the left, and the highway is now nearly in line with the Tumbler's direction, running into the distance next to the office building, and passes along the left side of the shingled roof, making it easy for the Tumbler to leap easily onto the roadway.

Continuity: After the big explosion, Bruce is shown holding Ducard at the edge of the cliff. Bruce's body is over the edge, only his arm remains on the ice to anchor them. But as he lifts Ducard to safety, Bruce's body is suddenly on the ice, only his right arm is over the edge.

Deliberate "mistake": When Batman flees from Gordon after their first meeting, he leaps across an alley and catches himself on the railing on a fire escape. This fire escape fails, dropping him (as well as the clothing left to dry on the railing). Batman grabs the next railing and again, this second fire escape collapses. Exactly the same as the first, with the same clothing falling off. When he climbs onto the 'third' fire escape, we see he's only come down one level, not two. The scene was artificially lengthened by using two perspectives of the same stunt.

Continuity: When Bruce defeats the Ra's impostor, the overhead beams collapse down as Ra's rolls onto his left side, head turned further left toward the floor to shield his face. As this shot ends, the debris settles, and we can see Ra's does not change position. But a close-up shows that Ra's is now flat on his back, head turned to his right.

Continuity: As Ducard is sliding down the ice toward the cliff, he's on his front, sliding feet first. Bruce is also on his stomach, but sliding head first. Then, just before Ducard goes over the edge, Bruce is instantly on his back, sliding sideways, right side toward Ducard, just in time to take Ducard's hand, saving him.

Continuity: As Ducard goes over the cliff's edge, Bruce is dragged over the edge in the distant shots, with only his left arm still on top of the cliff, holding the knife in the ice. But the close-ups (prior to the big explosion) show only his right arm and leg are over the edge with Ducard, while his body remains on top of the ice.

Continuity: As Bruce and Rachel talk inside her car in front of Falcone's building, he takes out his revolver. His hair is rather neat, parted in the middle. Rachel slaps him twice, and each time, his fair falls further onto his forehead from the sides so that it now hangs over his eyebrows. But an inserted shot, just before Rachel says "Your father would be ashamed of you", his hair is back in neat, before-the-slaps condition. After she says her line, his hair is properly messed up again.

Continuity: As Ducard slides down the icy slope toward the cliff, a brief shot from Bruce's viewpoint shows Ducard from a top-down perspective, revealing that Liam Neeson has been replaced by a stuntman with far more hair and no sign of Liam's receding hairline.

Continuity: When Batman is chased by the cops while he is trying to save Rachel, he reaches the roof of a parking lot and stops. A cop orders him to switch off the engine of his vehicle and get out. Later when Batman is chased inside a tunnel, we see a cop asking on his radio what the Batmobile looks like. The Batmobile then zooms past him and he says "never mind". The only problem is that it's the same cop both times, so he knew full well what the Batmobile looks like when it stopped in front of him initially. Probably caused by the order of those sequences being switched in editing, but still a mistake.

Revealing: Near the end of the scene, when Bruce and Fox are in the tumbler Fox says "We never could get the damn bridge to work, but this baby works just fine" then Bruce turns the wheel to the left but the tumbler turns right.

Continuity: When Bruce is thrown off the truck when released from prison, you can see his bag in the background as he rolls at least 5 feet away to his right. When the angle changes and he's getting up, the bag is right in front of him, if not slightly to his left.

Continuity: Almost at the end when Bruce and Rachel are talking where Wayne Manor used to stand, she puts her hand on his cheek/jaw/ear area. The position of her hand changes between shots, from having his ear between her fingers to having her fingers below his ear and so on.

Revealing: When Bruce Wayne is heading to the hearing at the courthouse, he checks his revolver to make sure it's loaded. His intent is to execute Joe Chill for killing his parents, so he would need a working gun. But when he opens the cylinder of the revolver to make sure it's loaded, you can see that all of the bullets have had the primer removed (the end of each bullet casing has a hole in it.) This is done to make each round impossible to fire, for safety on the set.

Revealing: When Bruce is told to execute the man in the ninja temple, watch the blade closely as he raises it up - the edge is ground down flat for the safety of the actors, he wouldn't be able to cut butter with that sword.
