Continuity mistake: When Max talks to the bakery clerk, the plate of rolls on the counter moves, depending on the shot. (00:57:20)
Continuity mistake: When Max and 99 are fighting Dalip on top of the bakery, Dalip punches a hole in the wall beside 99's head. When he body slams Max, the hole has disappeared. (01:04:55)
Continuity mistake: In the plane's bathroom, Max shoots himself several times with the mini-crossbow: in the cheek, ear, etc. After landing on the ground, all traces of the dart punctures are gone.
Continuity mistake: In the sequence of the laser rays, Agent 99 comes out of the sewer with her shoes on. Never the less, when she begins to do her stunt to cross without touching the lasers, she has them off. Then when she has crossed, she has them on again, but we never actually see her take them off or carry them while she is crossing.
Continuity mistake: The Chief flies in a fixed undercarriage Cessna aircraft. During some of the flying sequences, the aircraft is shown as a tail-dragger with retracted undercarriage.
Continuity mistake: When Agent 99 and Max are fighting the guards in Kristic's house, the hole Max and 99 used to get in disappears and reappears randomly.
Continuity mistake: Towards the end of the film, Max and Agent 99 are in various different dramatic scenes in an industrial area, thus dirtying their clothes. However, on their way to Disney Hall afterwards, their clothing is in a clean, spotless condition.
Continuity mistake: The skydiving sequence between Smart, 99 and Dalip is a mess of continuity errors; obviously the product of multiple takes/jumps. It begins over fields with no clouds below them, then on each subsequent shift in camera angles the area below them is either completely cloudy or clear. Then they fall through the clouds (which were not there originally). After coming through the bottom of the clouds the scene continues to shift between them falling to a cloudless background and a cloudy one.
Continuity mistake: When Max drives the Secret Service vehicle through the golf course, the driver's side door mirror is broken off. It then changes back and forth from hanging limply by a few wires to securely fastened on the door. (01:30:20)
Continuity mistake: When Max is in the bakery, his gun keeps switching around. From a SIG to a Beretta to a Glock, then back to a SIG.
Continuity mistake: Back at the KAOS Headquarters when Siegfried finishes with the phone call he turns around to speak to the big man. The violin jumps from under his right arm to him holding it in his left hand. (00:51:15)
Continuity mistake: In the plane's bathroom, when Max is about to be sucked out of the plane, he has his swiss army knife in his mouth. But in the next shot, the bird's eye view of him being sucked out, his swiss army knife vanishes. It's foreseeable that in between shots Max uses his hands to pocket the knife but both the speed at which he would have to do it and the fact his hands are still clenched in the same position they were in the previous shot makes it very unlikely.
Continuity mistake: Prior to Max being sucked out of the plane, he holds his knife in his mouth. When he is ejected, he is still carrying it in his mouth. He screams, however, and the knife should have fallen. But Max supposedly still has the knife later in the movie. (He tells 99 to take his knife from his pocket.) It is possible he pocketed it, but unlikely, as stated in a previous mistake.
Continuity mistake: At the end, when Agent 91 and Larabee pick on Hymie for being the new guy, there's a shot where Agent 91's badge is flipped. It's after Larabee says "new guy did", the badge is clipped on backwards. It's facing forward in the other shots.
Continuity mistake: When the bomb in the piano is first armed, it has a simple LED display reading "ARMED." Later when the Ode to Joy starts, it has a complex graphical display counting down.
Continuity mistake: When Max and the Chief are in the plane, the banner is attached to the cable at the end where it says "IT." When they go low and Max is by the yellow truck, the banner is now attached at the opposite end, where is says "suicide." In later shots it's attached back the other way.
Continuity mistake: When Max is entering CONTROL through all of the doors and a paper gets caught in one, the paper is moved out of frame as a whole piece of paper. When the camera moves up, the paper is now ripped in half. Even though you hear a ripping noise afterwards, enough time has not passed for the paper to be ripped and it is one continuous shot.
