Revealing: The Thrush guard Solo & Illya toss over the bridge railing during their escape from the compound is a little too obviously a dummy. (Timecode) Submitted by Jean G

Revealing: At the very end, in Waverly's office, the boom shadow is prominently visible on the door. (Timecode) Submitted by Jean G

Factual error: Solo blows open the ceiling vent of Illya and Marion's cell, and she stands on Illya's shoulders until Solo can reach her and pull her out. This leaves Illya with nothing/no one to stand on, no way to reach the vent and no apparent way out of the cell. But he's out just the same in the next scene, with no explanation as to how. (Timecode) Submitted by Jean G

Continuity: Aboard the yacht, Solo tucks his gun into his waistband. Next shot, as he takes cash out of the box, the gun has disappeared. It reappears in the shot after that. Submitted by Jean G

Continuity: In Waverly's office, Illya hones his combat skills by swinging at a suspended wooden block with a baseball bat. When the alarm goes off, Illya puts the bat down on the table, and he and Solo rush to the computer console. In the next, reverse angle shot, the block is still hanging from the ceiling, but the baseball bat has vanished from the table. Submitted by Jean G

Revealing: When they're fleeing down the side of the mountain, Illya and Marion gain a sudden 25 lbs. each, thanks to the use of two very conspicuous stunt doubles. (Timecode) Submitted by Jean G

Continuity: When Danfield opens the briefcase, the bundles of money inside are disarrayed, and he jumbles them further. A few shots later, though he hasn't touched them again, they've straightened themselves into nice, neat piles. (Timecode) Submitted by Jean G

Revealing: Every time the villains' deadly gas, "hydro," is mentioned, the word is badly and very obviously dubbed in, and doesn't match what the actors' lips are saying. This occurred because the original name used, "freon," turned out to be an existing (and patented) refrigerant gas, so the name had to be changed to avoid a trademark lawsuit. (Timecode) Submitted by Jean G

Revealing: Here, in the opening scenes at U.N.C.L.E. headquarters, as well as in a number of other first season episodes, the unmarried Illya is inexplicably wearing a wedding ring. (Timecode) Submitted by Jean G

Revealing: Illya's stunt double during the balcony fight is painfully obvious: his face and bad wig are visible throughout the scene. (Timecode) Submitted by Jean G

Factual error: Supposedly engraved on a ceremonial sword is the wrong date - 1443 - for the fall of Constantinople. That happened in 1453. (Timecode) Submitted by Jean G

Factual error: For a supposed language expert, Illya speaks very poor German. Entering the night club, he introduces himself with the line, "Ich bin Herr Strickland." That's terrible grammar. It should be, "Ich heisse Herr Strickland." (Timecode) Submitted by Jean G

Continuity: The gas-spewing suitcase that Solo tosses off the stopped train is gone a minute later when Stryker and Miss Parsons jump to the ground. (Timecode) Submitted by Jean G

Continuity: In the intro, Illya gets into the car and as he's talking to Solo, finishes the last of his breakfast donut in close-up. When we cut to a two-shot, he finishes the donut all over again. (Timecode) Submitted by Jean G

Continuity: When he's on the hospital gurney, Stryker's hands are extended over his head in one shot, and in the very next, they're tucked down under the covers. (Timecode) Submitted by Jean G

Continuity: In the opening scene, the camouflage make-up smeared on Illya's face is completely different in close-up than it is in full shot. (Timecode) Submitted by Jean G

Plot hole: The typewriter case containing the secret plans is said to be boobytrapped with nitroglycerine. If dropped, says the Thrush agent, it "could blow us all up." Yet it survives a plane crash intact and is later wielded as a club several times in the cavern fight scene, and somehow it never explodes. (Timecode) Submitted by Jean G

Continuity: Solo, Illya and Zia get out of the car and run into the woods, leaving the rear passenger-side door standing open. When they return, the door has somehow closed itself. (Timecode) Submitted by Jean G

Continuity: When they're being chased by the dogs, Illya pulls off Marion Raven's shoes so she can climb the tree. He tosses the shoes into the pool below. But in the next shot, as Marion begins to climb, her shoes are back on her feet - that is, until they both leap from the tree into the pool. Then, her shoes are off again, and already floating in the water. (Timecode) Submitted by Jean G

Visible crew/equipment: In the woods in the dead of night, Illya opens his car door and captures the reflection of the big round studio light illuminating the scene. (Timecode) Submitted by Jean G
