It Takes One to Know One - S1-E2
Continuity mistake: While he hangs from the ceiling over the jewels, Al's trapeze is spinning slowly. But when the shot cuts to a close-up, you can tell from the stationary background that the trapeze is now perfectly still. In the next full shot, though, it's spinning again. (00:39:00)
The Galloping Skin Game - S2-E10
Visible crew/equipment: While Mundy is tying up the unconscious Willie, the boom shadow is moving back and forth on the wall at the upper right of the screen. (00:27:05)
Audio problem: One of the perils of filming on location is employing local talent with accents too thick to be understood. Here, both the Italian actors playing the kidnappers are very obviously dubbed over. (00:40:45)
To Sing a Song of Murder - S3-E20
Continuity mistake: At the airport, Mundy asks Marilyn what's wrong and places his hands on her shoulders. Then the shot cuts to a reverse angle, and his hands are resting on top of the car door instead. (00:07:50)
The Three Virgins of Rome - S3-E7
Continuity mistake: When Alister Mundy's three friends are retrieving the paintings at the end, a small black dog appears, seemingly out of nowhere, and between takes is suddenly trotting along beside them. (00:44:50)
The Funeral is on Mundy - S2-E20
Continuity mistake: After Mundy fights with Susanna Sutton, Sutton's shoe slipped off her foot. While she sits defeated, Mundy looks for a nearby cord to tie her hands. Despite not moving from where she was, her shoe reappears on her foot. (00:37:33)
Beyond a Treasonable Doubt - S3-E23
Audio problem: When Mundy escapes, Devon shouts, "Stop him!" But his lips aren't moving when we hear the words shouted, and when his lips do mouth the words several seconds later, there's no sound. (00:10:00)
Deliberate mistake: We see the Air Force plane's bomb bay doors come open. But in the next shot of the plane banking, the doors are instantly closed again. (00:45:20)
Factual error: Mundy makes a phone call by wiring a radio speaker to the wall jack. Clever, but it wouldn't work. He might be able to hear dial tone, etc., but no one he called would be able to hear him without a microphone/sound pick-up, which the radio didn't have. (00:16:15)
Flowers From Alexander - S3-E5
Continuity mistake: Sykes is drinking a beer when Nicholas knocks on the door, and he leaves the beer can on the balcony railing when he crosses to let Nicholas in. When they both walk out onto the balcony a moment later, the beer can has disappeared. (00:43:05)
Visible crew/equipment: When Madison and his political entourage walk down the hallway, the shadow of the camera precedes them, moving along the wall on the left. (00:06:10)
Revealing mistake: The saloon's upper level railing looks solid until just before the bad guy falls through it, when the cuts in the break-away section are prominently visible. (00:26:05)
Continuity mistake: When Botarelli gets up from the banquet table, a large orange, sitting beside his wine glass in close-up, disappears in the next, wider shot. (00:21:30)
Continuity mistake: Mona draws a heart in the dust on the bar and writes "Al + Mona" inside it. When we see a close-up it, however, the L is suddenly much larger than before, and the name "Mona" is written in smaller letters. (00:04:00)
Continuity mistake: Angela's limo picks up Mundy and drives down a tree-lined country road. But in the very next shot, the view out the back window is of a busy city street with nary a tree in sight. (00:13:00)
