Continuity: Number 14 has to push a button to activate the first tape she puts into the player. She then puts on the 'A' tape and it starts playing by itself, with no button pushed. When she puts in 'B,' though, she has to push the button again.

Continuity: During the dance, the bottle of wine on Number 6's table is sitting on the left side. No one touches it, but when he and B come back to the table, the wine has moved itself to the center.

Continuity: When Number 6 kicks out the grill, his socks are blue. In the next shot, though, the socks have turned brown.

Continuity: The length of A's cigarette varies considerably between takes. It's short in long shot, then gets suddenly longer in the following close-up.

Continuity: Number 6 substitutes clear water for the red-tinted drug in the syringe. But when Number 14 later injects him with the same syringe, the fluid in it has turned red again.

Factual error: When he breaks into the secret lab, Number 6 finds the syringe and substitutes plain tap water for the drug to be used on him. But even a small injection of unpurified, non-saline water can cause severe pain and is potentially lethal: it can cause oxygen bubbles to form in the bloodstream, and if this air embolism reaches the heart, cardiac arrest can result. Certainly not a risk Number 6 would take. (See http://en.wikipedia.org/wiki/Air_embolism.)

Continuity: Throughout the episode, Number 6's lapels switch from having solid to broken white piping and back again.

Continuity: Number 2 has a nice, bright red handkerchief peeking out of his pocket when he leaves the house. But between shots, it turns itself into a blue handkerchief.

Audio problem: During the campaign, the marching band is striking up a lively tune, and the bass drummer is pounding away on his drum - but there's no drum beat in the sound mix.

Continuity: While Number 6 and the maid are in the kitchen, the toast rack moves itself several feet in between takes. It's on Number 6's right, then suddenly appears on his left instead.

Continuity: The sequences of Number 6's campaign speech scene were apparently filmed several months apart from each other. The trees behind him change from Springtime bloom to Winter bare and back again continually.

Continuity: Number 2's long neck-scarf changes when he steps into Number 6's house. It gets longer on the right side after he comes in the door.

Continuity: Number 6's bed tidies itself in the scene where the spying lamp is lowered from the ceiling. First the bedcovers are rumpled and disarrayed. Then in the next shot, all is straight with the blanket neatly folded at the foot.

Continuity: Number 6 grabs the boat hook and pulls the mechanic into the water. With a sudden shift in camera angles, the hook instantly vanishes from the falling man's hands.

Revealing: Stock footage puts Number 6 in two places at once when he grabs the bull-horn and starts shouting at the Villagers to go. There's an inserted shot of the plaza from "Arrival" that includes Number 6 walking through it on his first day in the Village.

Revealing: Though there aren't supposed to be any "normal" automobiles in the Village, there are several visible in this episode, parked in the background. Look closely behind the campaign placards as the golf cart/taxi moves, and behind Number 6 as he leaves the exchange. Several more can be seen behind 6 when the cameraman approaches him.

Continuity: It's high tide when Number 6 escapes in the boat, but when he's brought back just a few minutes later, the tide is out.

Revealing: Rover flies down from the Green Dome, and briefly reveals his true identity as a weather balloon. His air nipple and guide wires are both showing.

Continuity: The number of toast slices in the rack on the breakfast cart changes between shots. Number 2 takes a piece, leaving three. No one's gone near the cart, but a moment later, the toast rack contains five pieces.

Visible crew/equipment: Watch the water at the lower left of the screen as Number 6 makes his speedboat escape attempt. You can see the wake created by the camera crew's boat.
