Continuity mistake: When the lamp begins spying on him, Number 6's bed sheets and blanket rearrange themselves from messy to neatly tucked in between shots.
Continuity mistake: Alison is thanking Number 6 for letting her practice on him. In close-ups, her hands are at her sides. But in longer shots, she has her hands folded under her chin.
Revealing mistake: In the aerial shot from the helicopter as it overflies the Village, another "real world" car can be spotted parked next to the Green Dome.
Factual error: Alison's Polaroid pictures develop themselves instantly. (In reality, you had to wait just over a minute before separating the developer sheet and finished photograph.) She also leaves the same flash bulb in when she takes a second picture - and it flashes again.
Revealing mistake: Watch Curtis' shadow when he and Number 6 have their pistol range competition. The split-screen process cuts his shadow in half.
Revealing mistake: While they ride toward the helicopter, Number 6 and Number 2 have a conversation. Shots of Number 6 are obviously outdoors under windy conditions: his hair is blowing. But every shot of Number 2 has been taken in-studio with a rear-screen projection. His hair isn't moving at all.
Continuity mistake: Watch the helicopter when it first lifts off. It has regular "sled-style" landing struts. But in the air, it suddenly has water pontoons. When it lands again, though, the regular struts return.
Continuity mistake: When the Village doctors and technicians begin their procedure on the unconscious Number 6, one man folds the sheet and blanket back from his chest. A few shots later, the same man does this again.
Continuity mistake: While the technicians are prepping the unconscious Number 6, there's no watch on the lamp table by the bed. One appears there, though, when the tech begins collecting the prisoner's personal items.
Revealing mistake: Throughout the shooting competition between Number 6 and his Dopplegänger there are numerous shots where both Number 6's are facing the camera and you can see a jittery line running down the middle of the shot where the shots were poorly overlaid.
The General - S1-E6
Visible crew/equipment: During the street party, when the interviewer asks Number 6 questions about European history, you can see a microphone in the bottom right of the screen. (00:28:08)

Continuity mistake: At the end, the Professor and Number 12 fall dead on the ramp. Between shots, their positions change.
The General - S1-E6
Continuity mistake: 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.
The General - S1-E6
Continuity mistake: 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.
The General - S1-E6
Continuity mistake: 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.
The General - S1-E6
Continuity mistake: 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.
The General - S1-E6
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.
The General - S1-E6
Continuity mistake: 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.
The General - S1-E6
Continuity mistake: 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.
Revealing mistake: On the raft, when Number 6 starts to take apart his radio, you can see that the raft is in very shallow water but it's supposed to be out at sea. (00:10:25)
Answer: It's even more obvious than you think, you know who number 1 is in the very first episode. When 2 replies to the question "who is #1?" Change the way he answers from you are number one (in the monotone or accented answer to, "You are, number 6. The comma gives you the answer. #6 is #1. It's the tone of the answer.
