Visible crew/equipment: Mozart is composing The Requiem Mass when Constanze admits a late-night caller. The door she opens reflects a large, bright square of light that looks like a sun-lit window (only it's night) - or more likely, a studio reflector. (It's definitely not the burning candles. Wrong shape.). (01:55:00)

Visitors From Beyond the Stars - S1-E18

Continuity mistake: In the saloon, the table at the lower right of the shot has nothing on it. After a brief close-up of the bartender, we cut back to the master shot - and even though no one's gone near it, the previously empty table now has a candle in a tin holder sitting on it. (00:28:30)

Visitors From Beyond the Stars - S1-E18

Continuity mistake: An escaping Tony leaves the cell door standing open. But when the shot reverses angles, the door has mysteriously closed itself. (00:22:20)

Visitors From Beyond the Stars - S1-E18

Continuity mistake: Tony jumps onto a brown horse and gallops into town to warn the sheriff. He doesn't stop on the way, but somehow arrives in town riding a black horse instead. (00:12:45)

Visitors From Beyond the Stars - S1-E18

Factual error: The aliens show Doug and Tony the planet they plan to invade - Earth, of course. But the special effects department forgot to give poor old Earth any clouds. (There are clouds over more than 70% of our planet at any given time.) When they go down to the surface, though, there are plenty of clouds in the sky. (00:05:20)

Visitors From Beyond the Stars - S1-E18

Continuity mistake: When the aliens use their paralyzer on Doug and Tony, the time travelers are both bending forward. But in the next shot, they've somehow straightened up, despite being "paralyzed." (00:01:45)

The Second Time Around - S3-E11

Factual error: Wally's car phone operates just fine - without the huge exterior antenna it would have required in 1969. (00:12:50)

Give 'Em Enough Rope - S1-E2

Revealing mistake: Reid's rear view mirror, missing in all the medium shots (processed in-studio with an obvious rear-screen projection), mysteriously reappears in full shot when his Chrysler pulls into the car shop. (00:14:00)

Jean G

The Phi Beta Killer Affair - S1-E25

Revealing mistake: Mark's stunt double during the fight on the mansion's porch is a very close match for him - except for the fact that he's about 6 inches taller. This causes "Mark's" height in relation to the man he's fighting to fluctuate noticeably (taller than, shorter than, taller than again) between shots. (00:37:15)

Jean G

One Way to the Moon - S1-E2

Continuity mistake: Doug and Tony are being interrogated by the Mars Mission flight crew. In two-shot, they're standing shoulder-to-shoulder with each other, no more than a few inches apart. When the shot cuts to a wider angle, Tony is suddenly several feet away. (00:10:00)

Trivia: Throughout the series, many shots of the extensive time tunnel project are actually "borrowed" footage of the Krell laboratory complex from the 1956 film Forbidden Planet.

Devil's Island - S1-E9

Revealing mistake: During the final fight scene, Doug is struck by one of the guards and falls back against a rock. The huge boulder wobbles precariously when he hits it. (00:44:50)

Jean G

Crime Wave - S1-E4

Continuity mistake: Kato activates the clamps that prepare Reid's car for the flip-over that will reveal the Green Hornet's "Black Beauty." We see the clamps hook themselves to the car in close-up. But in the next, wider shot of the car turning over, the clamps have disappeared. (00:05:00)

Jean G

Trivia: According to his creators, Britt Reid is a descendant of the Lone Ranger's nephew, Dan Reid. Apparently the "masked man syndrome" ran in the family.

Merlin the Magician - S1-E27

Factual error: Wogan the Viking probably shouldn't laugh quite so enthusiastically. When he does, several of his very 20th Century gold fillings are visible. (00:09:30)

Jean G

Merlin the Magician - S1-E27

Continuity mistake: Arthur ties a rope around the battlements and descends the tower's west wall. Tony then waves a torch to signal the soldiers to attack. He's standing at the same spot Arthur left from (the rope is still tied there), but in the long shot, his torch is waving from the tower's south wall instead of the west one. (00:41:15)

Jean G

Merlin the Magician - S1-E27

Deliberate mistake: Here, as in many other episodes, Doug and Tony are time-shifted wearing period (in this case, Viking) clothing. But they tumble into their next adventure magically wearing their left-behind 20th Century clothes again. (00:45:30)

Jean G

Town of Terror - S1-E30

Continuity mistake: The alien freezes Doug and Tony and escapes to the cellar. But when the shot cuts back to the time travelers, they're standing much farther apart and are posed in different positions than they were when first frozen. (00:05:05)

Jean G

Raiders From Outer Space - S1-E29

Revealing mistake: This episode features borrowed scenes from the historical epic "Khartoum." Unfortunately, the movie footage is in uncorrected Cinemascope, making both the Arab and British armies look bizarrely skinny. (00:14:15)

Jean G

Deadline for Death - S1-E12

Revealing mistake: The Black Beauty, Hornet's car, releases a smoke screen to stop the bad guys' plane from taking off. But you can see in several shots that the stunt car actually releasing the smoke is an entirely different make, model and color. (00:21:30)
