Continuity: When Mrs. Peel and Steed are playing chess, some pieces are on the wrong squares.

Revealing: In his castle, Sir August de Winter has a world globe with Newfoundland mentioned twice.

Continuity: Sir August DeWinter confronts an assembled United Nations Council (or something like it) and makes his demands for money. To prove his power, he unleashes a blizzard on the building. Unfortunately, the Council room has giant windows, and when we look outside, we can clearly see that it is a sunny day with emerald green trees.

Other: The shot of Big Ben destroyed by lightning looks strangely like the Big Ben exploding in the film "Mars Attacks" (1996).

Continuity: When John Steed and the Invisible Man are talking, the man takes a folder and opens it, but doesn't moves the file in it. In the next shot, the file is open.

Factual error: Whilst impressive, the snow covered set of Trafalgar Square is still far too small.

Revealing: Each time a robotic insect explodes in the forest, it stays in the air as if a thread retains them.

Continuity: There is a scene where Mrs. Peel is trapped in the White Room in DeWinter's mansion. Above the fireplace is a mirror. Cut to the outside, where Steed walks. He approaches a window and taps his cane on it, revealing that the windows are fake. They are simply brick or concrete painted to look like windows. Back into the White Room. Mrs. Peel hears the tapping and locates the source at the mirror. She runs and dives into the mirror and it shatters, and she somehow ends up outside next to Steed. Remember that there where no glass windows. Did she break through the bricks?

Continuity: When Mrs. Peel is playing the piano and the camera angle moves to her face, the piano keys inside are not moving. Even if it is a player piano, the keys inside have to strike the strings to make a sound.

Continuity: Near the end, when Steed and Peel are crossing the river in the globes, the globes have support struts to keep them spherical. When they arrive at the island and are unzipping and deflating the globes, the support struts have vanished.

Continuity: When Emma Peel and John Steed are fencing in the shop, Emma grabs John's fist at some point. His sleeve moves significantly in the next shot.

Continuity: When Peel and Steed are being chased by the bees, there is a shot looking down the road to their car. As they swerve you can see that there are 3, maybe 4 people in the car when there should only be 2.

Factual error: Each time somebody has snowflakes on them, they don't melt.

Continuity: During the chase scene where Steed and Peel are fleeing the robot bees in the blue Jaguar, one of the Jag's doors disappears between shots. We never see the car lose the door or take a hit that might inflict that particular damage.

Continuity: When the henchmen leave after the fight behind the Wonderland Weather building, Steed notices a map on the ground. It moves by itself between shots, and there's no wind.

Continuity: Right after the fight in the maze, John Steed's umbrella is going to fall on a bush. In the following shot, it lands directly in his hand.

Continuity: When John Steed wake up in Emma Peel's apartment, there are fewer grapes in the bowl when she goes to the piano.

Continuity: When the mechanics attacks Steed in the first scene, they push the door open. It is locked when he has finished with them.

Other: When Peel is serving tea to Steed, the sunlight is so strong that you can see through the cups. There's no liquid at all in them.
