The Avengers (1961) - 12 mistakes in entire show

Revealing: In the midst of Steed's conversation with the wrestling referee, the camera loses focus and suddenly whip-pans away when it shouldn't. The actors continue their lines as the camera comes quickly back and refocuses on them.

Revealing: The secretary turns on the tape recorder to play back her employer's dictation. His voice starts speaking, but the tape reels aren't turning, and the button she pushed hasn't stayed depressed. Apparently, the machine isn't even on.

Continuity: When Steed, Mrs Peel and their travelling companion Mr Smallwood arrive at the pub, it is pitch black. However, when Smallwood leaves a few minutes later to go and visit his brother, it is fairly light again. All subsequent shots of him outside continue to be well lit, whilst in the shots looking out from the pub it is dark.

Revealing: When Steed comes out from hiding behind the spiral staircase and wall, the rim of his hat touches the wall, which wobbles, revealing a fake wall. It's very noticeable, because there is a shadow cast from the staircase to the wall where you can see it moving.

Revealing: When Steed and Mrs Peel are fighting one another, the stunt doubles used bear absolutely no resemblance to the actors.

Continuity: When Steed and Emma are driving to the estate, the car's windscreen keeps disappearing. It's there in full shots, gone in close-ups, and reappears again every time we cut back to a long shot.

Visible crew/equipment: When the old lady enters the costume shop to retrieve her knitting book, an equipment shadow sweeps across the lower right of the screen, then moves back to the left.

Continuity: Mrs. Peel is nibbling at a bunch of grapes. Every time the shot cuts to full, there are more grapes on the stem than in the close-ups.

Continuity: Steed tosses his opponent over his shoulder during the scuffle. The man lands on his back with his right hand extended over his head. But when the shot cuts to a different angle, both his arms are instantly down at his sides instead.

Factual error: The bad guys are supposedly auctioning off the stolen Mona Lisa. But they and their prospective buyers aren't very art savvy. The painting is more than twice the size of Da Vinci's actual masterpiece.

Continuity: When Mrs. Peel drives to Jordan's house, she parks in front of the house. When the assassin arrives shortly after, her car has disappeared.

Continuity: When Steed begins cutting Mrs. Peel's bonds, they're black straps. When he finishes sawing through them, however, they've turned into ropes.
