In His Image - S4-E1
Revealing mistake: In the basement lab scene at the end, George Grizzard's double's face is visible in profile several times. (00:38:50)
The Thirty-Fathom Grave - S4-E2
Factual error: On the bulkhead of the ship's sickbay is a standard 12-hour civilian clock. It shouldn't be there. All clocks aboard U.S. Navy vessels show 24-hour military time. (00:31:20)
Revealing mistake: We see Redfield's car strike the invisible barrier from a side angle. It jerks to a stop and the hood flies up, but there's no other front end damage - until the angle shifts to a forward view, a shot of an identical car that had been previously wrecked. Now there's suddenly considerable damage to the front end, and the hood is in a different, much more crumpled position. (00:11:10)
Continuity mistake: As Ilse walks toward the front of the classroom, she passes the kids in the last row and is even with the kids in the next-to-last row, but in the following shot, shown from her point of view, she's passing the kids in the last row again. (00:30:45)
Death Ship - S4-E6
Revealing mistake: When Mason puts the ID card back into the pocket of his dead duplicate, the "corpse" twitches its eyelids. (00:14:30)
Death Ship - S4-E6
Visible crew/equipment: Just after the ship re-attains orbit, the shadow of a production crew member moving his arm can be seen on the wall at the upper right of the shot. (00:38:30)
Death Ship - S4-E6
Visible crew/equipment: In the final shot of the ship ascending into space, one of the filament lines supporting the model is showing just above the saucer. (00:44:15)
Continuity mistake: When Jackie leaves the office, the clock reads 10:12. The ensuing continuous scene with Winter and Mr. Smith is almost 6 1/2 minutes long, yet at its end, the same clock has advanced only 2 minutes, now reading 10:14. (00:33:00 - 00:39:15)
No Time Like the Past - S4-E10
Factual error: The U-boat has a spinning sonar mast. Subs in 1915 didn't have that.
Continuity mistake: When Mr. Ferguson is measuring the wax figures, he's shown holding a tape measure up against the figure of Landru (the one holding the rope). In the next shot, the figure is shown with no one near it. The next shot again shows Mr. Ferguson measuring the figure. (00:45:35)
Of Late I Think of Cliffordville - S4-E14
Other mistake: Mr. Feathersmith sells the 1403 acres to Mr. Hecate for $40, so he can pay Devlin to send him back to his own time. $40 in 1910 would be about $1,127 today and it's extremely unlikely that anyone, especially a man like Hecate, would have that much money on them. (00:47:45)
Of Late I Think of Cliffordville - S4-E14
Other mistake: When Feathersmith meets Devlin it's 1963, and he's 75 years old, which means he would have been born in 1888, so in 1910 he would have been 22, not 30. Otherwise, he'd be an 83-year-old man.
Of Late I Think of Cliffordville - S4-E14
Revealing mistake: When the camera is in a close up on Feathersmith's face, you can see the line of the skin wig he wore to be older.
Of Late I Think of Cliffordville - S4-E14
Other mistake: Miss Devlin tells Feathersmith the cost of his trip, including the historically accurate maintenance of the town Cliffordville and its citizens, but line doesn't make any sense, the town is not a recreation since Feathersmith is being literally sent back in to time, the town can't be anything other than accurate.
Of Late I Think of Cliffordville - S4-E14
Factual error: Even though its supposed to be 1910, the banker's daughter plays a 1960's Steinway piano.
Of Late I Think of Cliffordville - S4-E14
Revealing mistake: When the camera is in close up on Feathersmith, the line of the skin wig is clear.
The Incredible World of Horace Ford - S4-E15
Factual error: In the opening scene, Horace painstakingly loads his six-shooter cap pistol with a six-cap round - then shoots his boss with it seven times. (00:00:40)
On Thursday We Leave For Home - S4-E16
Factual error: The colonists' planet has twin suns and, we're told, no night. We see the suns, side-by-side in the sky. But twin suns would not create perpetual day. Night/day is caused by the rotation of the planet on its axis, regardless the number of suns. In a binary star system, the two stars orbit each other around a central point in space. The planets would orbit around that central point too. In order for there to be no night, the planet would have to pass between the two stars, a process it would not survive. The gravitational forces of two opposing suns would tear the planet apart. (00:18:35)
Suggested correction: This assumes that all planets orbit along a Sun's equatorial plane, which they don't. In fact Earth's orbit is 7° off on either side of our Sun's equatorial plane. Also taking into account the tilt of their planet, it's likely that experience a similar phenomenon to that of Alaska, although for much longer, where their orbit and position don't allow their side of the planet to see darkness.
On Thursday We Leave For Home - S4-E16
Visible crew/equipment: As the men talk in the cave, the boom mic is plainly visible.
Passage on the Lady Anne - S4-E17
Continuity mistake: During their conversation over tea, Mr. McKenzie tells the Ransomes about the other people aboard ship. One elderly couple, the Whiteaways, are sitting in the background in almost complete shadow - until McKenzie introduces them. Then we see them in sudden brilliant light, and they've shifted their seating positions relative to the table. When we cut back to the master shot, they're back in shadow and back in their original positions. (00:29:55)
