Continuity mistake: In the water tank sequence Cranston dives to the bullet holes to get air. When he dives down there is a camera shot looking up at him from the bottom of the tank showing that there is plenty of air left at the top, no doubt left there so that the actor would not drown. And; for the sealed tank to fill completely there must have been a way for air to escape rapidly from the top. When the tank was full water kept pouring in and would have escaped the same way. When Margo arrives there is no water coming off the top of the tank.
Suggested correction: The tank is to test pressure. Had water been escaping so would have Cranston.
Continuity mistake: In the scene on the bridge near the beginning, when we first see The Shadow, he's only wearing a coat, not his cape. The shot switches, and when we again see The Shadow, he now has a cape. The cape must have been a CGI effect, because trailers and commercials show the same shot WITH the cape.
Continuity mistake: When Claymore shoots the invisible Cranston (The Shadow) in the water tank, a small volume of blood immediately starts dripping into the water. When Cranston materializes seconds later there is no blood whatsoever on him and no blood comes off him or his clothing when he dives into the water.
Continuity mistake: As the atomic bomb is being deactivated, the floor is stationary. When the bomb casing drops to the floor, the floor is rotating, and sends the bomb down the hallway. (01:35:30 - 01:36:00)
Continuity mistake: In the scene where Reinhart Lane finally defuses the bomb, he clips the red wire and Margo yells out "Green." and his hand holding the clippers are just above the red wire. In the next shot, his hand is nowhere near the wire and it changes back and forth during the rest of the scene.
Continuity mistake: During the bomb deactivation, the countdown clock is not in sync with the editing. Bomb clock is at 1:02:54 and counts down to 1:02:50, but at next shot ten seconds later the timer is at 1:03:00, a relapse of ten seconds. (01:35:20)
Continuity mistake: At the Cobalt Club, when Margo asks Commissioner Wainwright about her father, a dinner fork suddenly appears in his right hand.
Continuity mistake: The dinner fork that was in Wainwright's hand suddenly transforms into a martini glass as Margo discusses her father with him.
Continuity mistake: A thin beaker suddenly appears next to the glass container Dr. Tam uses to test the coin Cranston gave him to test.

Continuity mistake: As Claymore is complimenting Margo on her dress, he stops her, positioned at her right shoulder, but the next shot shows Claymore further to her left front.
Continuity mistake: When Berger hands the desk lamp to Nelson, Nelson holds it down to his right side, but the next shot has him holding the lamp across his abdomen.
Continuity mistake: When Claymore is shooting at Cranston, he misses three times, creating three bullet holes in the tank on the side opposite the door. When the tank fills Cranston swims over to them to get air, then swims across the tank to the door. When Margo Lane arrives and walks up to the tank the bullet holes have moved across the tank and are now next to the door. When Margo opens the door and the water rushes out of the tank the bullet holes next to the door have disappeared.
Continuity mistake: Near the beginning of the film when the police are investigating Shiwan Kahn's now empty coffin watch the policeman that delivers the message to the vacuum tube system. His ring starts on his right hand then switches to his left and so on. It's really funny. (00:34:03)
Continuity mistake: In the museum, the officer directing Wainwright has the ring on his right hand. A moment later, it's on his left hand.
Continuity mistake: At Cranston's penthouse, Margo approaches and stops directly in front of Cranston, but the next shot shows her standing off his right shoulder.
Continuity mistake: When Cranston exits Moe's cab to check out of the empty lot, Cranston is standing inside the cab's open door, then the next instant shot shows him standing outside the door before he closes it.
Continuity mistake: When the the old Asian guy is about to draw a picture of an atomic bomb on his blackboard, he clears a small section at the top of the board, and you can see some diagrams uncleared in the centre of the board. Yet when the camera shows his picture, the diagrams in the centre have now magically disappeared.
Continuity mistake: When Claymore is trying to stall Margo in the hallway, he rests his left arm on the wall, but his arm changes position as the scene cuts.
