Visible crew/equipment: As Hadley stands near the lockers, talking to Larkin and packing, the boom shadow dips into the shot over his head. (00:28:35)
Visible crew/equipment: When the black Ford pulls up to Minns' apartment building and Ballard gets out, several studio lights and reflectors are mirrored in the car's shiny surface. (00:48:25)
Character mistake: Someone in the set decorating department must have failed first-year Spanish. The name of the apartment complex (Spanish for "The Flowers") is prominently displayed over the archway, but has both words misspelled, reading "Los Floras." It should be "Las Flores." (00:06:20)
Continuity mistake: Andy's car crashes into a boulder in the beginning and stalls. But when he gets the engine started and drives away at the end, there's no damage at all to the front end of the car. (00:49:30)
Cold Hands, Warm Heart - S2-E2
Factual error: Barton's ship, we're told, has been designed only to orbit Venus, not land there. Yet he somehow lands anyway - on a planet with atmospheric pressure and broiling temperatures that should have crushed and incinerated him instantly. (00:25:30)
Visible crew/equipment: A glass shield used to protect the camera from a styrofoam rock slide shows us the ghostly reflections of several film crew members, including one wearing an enormous "10-gallon" cowboy hat. (00:31:30)
Visible crew/equipment: After Roy forces Peter to drink the formula, the boom shadow makes a very intrusive appearance on the wall above them. (00:42:40)
Behold, Eck! - S2-E3
Plot hole: Eck gives Dr. Stone one of his eyes so the scientist can create a lens to improve the alien's vision. At the end, Stone hands Eck the lens, but not the eye. When Eck puts on the lens, his missing eye reappears out of nowhere. (00:48:30)
Behold, Eck! - S2-E3
Continuity mistake: Eck tears a leaf from Stone's notebook. But the close-up insert of the page and the following shot of it being torn out reveal two completely different sheets of paper. The first has only a brief list of four names and addresses. The second is covered with handwritten notes. They don't match, yet they're supposed to be the same page. (00:04:05)
Cold Hands, Warm Heart - S2-E2
Revealing mistake: This 1964 episode is supposed to take place in its own near-future (the late 1960s). But some of the shots in the beginning reveal the use of outdated stock footage. During the parade, there's a close-up of a 48-star US flag, a relic even in '64, as Alaska and Hawaii became the 49th and 50th states in 1959. Old flags are supposed to be burned, and wouldn't have been used for civic events such as ticker-tape parades. (00:00:50)
Cold Hands, Warm Heart - S2-E2
Factual error: While orbiting Venus, Barton receives instant responses to his radio communications with Earth. At that distance, there'd be a transmission delay: at least 7-8 minutes. (00:25:00)
Cold Hands, Warm Heart - S2-E2
Revealing mistake: Mismatched stock footage puts the Venus-bound Barton in four different spaceships during his journey. We see brief shots of a Vanguard rocket launch, an Atlas missile, a V-2 rocket sequence, and finally, special effects shots of the ship borrowed from the 1950s SF series "Men Into Space." Not one of these vehicles even remotely resembles any of the others. (00:23:15)
Deliberate mistake: Amanda survives a plane crash into the ocean, hurricane winds in a life raft, then experimentation and attacks by giant microbes inside the alien probe. Yet when she and the others are rescued at the end, not one strand of hair is loose in her 1960s "beehive" hairdo. (00:49:05)
Deliberate mistake: Though by 1964 it was already suspected (and later confirmed by Mariner IV) that Mars has an atmosphere humans can't breathe and temperatures too low for humans to tolerate, Merritt and his crew are here exploring the planet sans spacesuits. This was "fudged" because space helmets A)are expensive, B)reflect cameras, and most importantly, C)obscure the actors' faces. (00:24:00)
Continuity mistake: When she's inside the giant test tube, Amanda raises her arms over her head. In the very next shot, with no time for her to have moved that fast, her arms are straight down and held rigidly at her sides. (00:36:15)
