Plot hole: When the watch is sucked to the island by the magnet, where was the sailor that the watch was attached to?
Revealing mistake: When Max and 99 are rowing away on the Chief's inflated diving suit, you can see that the Chief is not in the suit and it is just an inflatable raft.
Revealing mistake: Siegfried uses the magnet to push the ship away from the island. However, you can see the scene is reversed; the steam from the ship is going back into the funnel.
Revealing mistake: When Max accidentally shoots the life raft with the flare gun, he visibly doesn't make a hole in the raft. It's likely it's ink or ash or another black material to look like the raft had a hole burned through it.
Revealing mistake: When Max crashes through the wall in the prologue, you can easily tell it's a stunt double. You don't even need freeze frame to see it, as the screen freezes, stylistically fades, then the title sequence starts.
Audio problem: When Max crashes through the wall, he exclaims "A Baby?!"; however, his lips don't move.
That Old Gang of Mine - S3-E10
Visible crew/equipment: When the Turk is breaking into the palace, he pushes the window and it just swings open, since it is unlocked. However, you can see hands belonging to a crew member pulling the windows open to make way for the gag.
Ice Station Siegfried - S5-E13
Visible crew/equipment: Anytime the group of spies is walking out in the snow you can see the wall of the set that is supposed to look like fog.
Character mistake: Max reads the convict number on Big Eddie's shirt to the Chief as 14783652. But when we saw the shirt earlier, the last 3 digits were 285, not 652.
The Day They Raided the Knights - S4-E16
Continuity mistake: In Max's apartment, Max sneaks up behind 99 to give her a kiss. She punches him in the jaw and he falls back against the wall to the right of the doorknob. The scene changes to a close up of Max and he is sitting on the floor to the left of the doorknob.
Character mistake: Maxwell translates his famous line "And loving it' into the German 'Und damit gefreut'. Agent 99 who claims to speak German fluently confirms it. This translation is both far away from the meaning and doesn't make any sense at all. The right translation is 'Und liebe es'. (00:09:50)
Casablanca - S2-E6
Continuity mistake: When the chief stops Maxwell from beating the cab driver, he holds back Maxwell's arm by the very prominent cuff. After the following cut he holds it by the sleeve (and no sign of the cuff). (00:05:50)
Visible crew/equipment: When Max and 99 have reached the mansion, they both get out of the car to look in the trunk. As they start walking, some lightning occurs. If you look up at the top, you can see where the fake sky ends and the visible back of the stage begins.
Washington 4, Indians 3 - S1-E6
Other mistake: When Max tricks the Indian's daughter, he is supposed to say, "Now close your eyes and open your mouth". Instead he says, "Close your mouth and open your eyes". The Indian woman still reacts with closed eyes and open mouth.
Witness for the Persecution - S3-E3
Plot hole: In this episode, the villain makes a phone call to KAOS headquarters when he's captured demanding that they kill Max to stop him testifying in court against him. Later, several say that Max is the only witness to the villain's crimes, but the Chief and 99 were in the room when the villain made the call, so they could have been witnesses to "conspiracy to commit murder."
The Little Black Book: Part 1 - S3-E16
Audio problem: When Max is fighting the waiter, several times he misses the waiter completely, but you can still hear the sound.
Revealing mistake: At the start, when Max falls off his police motor cycle, he is obviously a stunt double.
Visible crew/equipment: Lights are reflected in the aide's glasses when Max and 99 are talking to him on the ground.
Revealing mistake: When the Prime Minister's aide falls out of the car, he is a dummy.
Audio problem: During the joust scene, Max turns around to have another charge at the Knight and the crowd is clapping, but there's no sound at all.
