Cold Hands, Warm Heart - S2-E2
Visible crew/equipment: Barton is terrified by a plant-like alien floating outside his spaceship window. The Venusian critter might be a heck of a lot scarier if it bore less resemblance to a furry stalk of celery - and if only its puppet strings weren't showing. (00:25:45)
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)
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 But some of the shots in the beginning reveal the use of outdated stock footage.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)
