Continuity: Number 6 holds the Penny Farthing pass in both hands in close-ups, but in all the master shots, he has it in just one hand.

Continuity: At the end, the Professor and Number 12 fall dead on the ramp. Between shots, their positions change.

Continuity: Number 6 is stabbed in the hand during his struggle with the projectionist. After he's treated for the injury, not only is he placed in an unnecessary sling (his arm wasn't broken), he's also suddenly bleeding from the forearm, several inches above the area where he was stabbed.

Continuity: At the Village cafe, the menu on the table turns itself 90 degrees between the master shot and the close-up. Number 6's hand position and one of the chairs also both change positions instantly.

Continuity: In the General's office, the professor pulls the sheet of paper he's been typing on out of the typewriter and inserts it head-first into the computer. When we cut to a close-up of the paper going in, however, it is now being inserted bottom-first.

Continuity: At the end, using only one finger of one hand, Number 6 types 4 characters on the typewriter. He then expressly states that what he typed was, "W-h-y question mark." But you can't type the question mark with one finger: it requires holding down the shift key.

Continuity: Number 6 is quite a quick-change artist. In the projection room, after the countdown reaches 2 minutes, he manages to: strip the unconscious technician; take off his own black suit, tie, hat and glasses; get into the white lab outfit, and finally, don all the communications gear in time for the 1-minute countdown announcement.

Factual error: When Number 6 types "WHY?" on the typewriter, the sheet of paper comes out with the word centered on the page. But the typewriter's carriage was pushed all the way to one end, so the word couldn't possibly have wound up in the page center.
