Revealing: When Maxwell drives the red Sunbeam Tiger out of CONTROL's foyer, you can see the added skid pan underneath the car to protect it as it jumps down the steps.

Continuity: 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: When Max talks to the bakery clerk, the plate of rolls she places on the counter moves, depending on the shot.

Continuity: When Max and 99 are fighting Felipe on top of the bakery, Felipe punches a hole in the wall beside 99's head. When he body slams Max and the hole has disappeared.

Deliberate "mistake": When Max and 99 are in the air, they can be seen talking to each other. This is not possible (as proven on MYTHBUSTERS) even if you were yelling at the top of your lungs. The wind would make any noise unrecognizable, yet we hear them talking to each other just fine.

Continuity: 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: 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.

Audio problem: In the scenes at the symphony concert, the orchestra is supposed to be playing Beethoven's Ninth Symphony. But in the first concert scene - a very quick snippet - they are playing Mozart's 40th symphony instead. Also, in the movie, both the Mozart 40th and the Beethoven 9th are seen employing a piano (although only the Mozart has the piano audible). In fact, neither of these symphonies requires a piano - there's no piano at all in the score of either one.

Factual error: When Smart falls out of the trap door in the airplane, they show an overhead view of him falling, shot from the ceiling of the bathroom. You see his body falling briefly before they cut the camera angle. With the speed of a commercial airliner being in excess of 600 miles per hour his body would have left the camera's view within a split second of him hitting the outside wind currents.

Plot hole: When Max is near Agent 23 on the helicopter roof pad, Max's watch geiger counter doesn't go off, but later, outside the Concert Hall building, it does.

Continuity: 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.

Factual error: When Max falls from the plane without his parachute it takes 99 over 30 seconds to make her jump (actually much longer because the scene was cut several times during her preparation to jump), yet she catches up to him in a few seconds. In actuality it would have been impossible for her to catch up to him. In the time it took for her to jump a commercial airliner would have traveled well over 5 miles. A previous corrector proposed that it would have been possible because Smart would continue moving in the direction of the aircraft after exiting it. Not true; a skydiver's lateral velocity drops to zero within a few seconds because of wind resistance. Also, Smart would have dropped well over 1600 meters in the time that it took 99 to jump. At the steepest decent angle and maximum velocity possible 99 could not make up the distance (sorry to mix standard and metric units here; I've researched this information on multiple skydiving websites).

Continuity: 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: 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.

Revealing: Obvious digital flames on the exterior shots of the SUV when it is on fire.
