Continuity: Malik begins peeling an orange with his dagger as Hubris threatens to brainwash Solo. But when the shot cuts, he starts peeling the same orange all over again.

Visible crew/equipment: When Hubris and his henchmen leave Narouz's bistro, the boom shadow is lurking on the block wall at the lower right.

Factual error: Solo's communicator starts transmitting all by itself. He's bound and tied when Illya calls, but somehow the "ring tone" stops and the frequency opens, allowing Illya to hear what the bad guys are saying, all while the unanswered and untouched device is still in Solo's pocket.

Continuity: As Mozart is forcing Illya to take him into U.N.C.L.E. HQ's basement, Mozart suddenly acquires, between shots, a security badge that wasn't there before.

Continuity: A swarm of bees blackens the windshield of Solo & Illya's car. We see them in all the interior shots, but every time it cuts to an exterior view, the windshield is perfectly clear.

Visible crew/equipment: The shadow of someone who's not in the shot intrudes on the right side of the screen as Solo exits the communications room and enters the corridor.

Continuity: Mozart and his henchmen invade the honey shop. Illya tosses a chair at them. One man falls. Cut to Illya firing his gun, then back to Mozart - and the man who fell is suddenly in a different place and position on the floor.

Continuity: Tavia writes a receipt and hands it to Mozart. She still has the red pen in her hand until the shot reverses angles. Then the pen instantly jumps from her hand to the counter several inches away.

Visible crew/equipment: After George's hypnosis and brainwashing are complete, the boom slips into the shot at the upper right corner of the screen.

Continuity: In close-up, Illya is covering the phone receiver with his left hand, but drops the hand to his side when he tells the operator, "Never mind." There's an immediate cut to a wider angle, and his left hand is suddenly back on the receiver in the same position as before.

Visible crew/equipment: When Solo enters the scanning room, the shadow of the boom assembly sweeps down the wall on the right side of the door.

Plot hole: U.N.C.L.E.'s yellow badges were worn only inside HQ, and were supposed to set off alarms if you didn't wear one, or if they were taken from the building. But here, Solo passes through security and walks out with his badge still on, and the alarms don't sound.

Visible crew/equipment: When Carla enters Waverly's office, both the boom mike and its shadow are prominently visible at the top of the shot.

Plot hole: Waverly installs the explosive ring on Solo's finger and arms it, then says, "No one is to know you've been issued a priority ring." Odd command. It's a huge and conspicuous gold and red ring that he can't take off, and everyone at U.N.C.L.E. knows what it is. So how can Solo possibly keep it a secret?

Visible crew/equipment: During his fistfight with the burly body guard outside Sir Norman's estate, Illya's stunt double's face is visible in profile.

Revealing: MGM often recycled props from its earlier films. Here, the head of Robby the Robot from "Forbidden Planet" is used as part of the rejuvenation machine.

Revealing: Illya's car collides with Madame de Sala's. But it's very obvious that the cars don't actually strike each other, and later shots of her vehicle show no damage at all where it was supposedly hit.

Continuity: At the end of Part 1, Sir Norman enters the rejuvenation device and immediately gets younger. As Part 2 begins, however, he emerges from the machine looking the same, and Dr. Gritsky says that his rejuvenation will occur gradually over the next few days.

Factual error: Dr. Gritsky over-rejuvenates himself at the end and turns into a young boy - who for some inexplicable reason still has the adult doctor's mustache.

Factual error: While Solo prepares the explosive, Waverly's line to Joanna is, "If you and I are wise like Lot's wife, we'd better not look." The scriptwriter got this backwards. Lot's wife was unwise and did look, and turned into a pillar of salt.
