The Rip Van Winkle Caper - S2-E24
Revealing mistake: The suspension machines are nothing more than large terrariums, there doesn't seem to be any electronics or piping or machinery of any kind attached to them.
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.
Other mistake: When Martin Landau throws the mini tape player to the floor, you hear the fast forward chipmunk sound but the reels are still spinning at the same speed as before.
The Odyssey of Flight 33 - S2-E18
Character mistake: The real speed that was reported was 3,000 knots. At one point, the plane encountered a bright flash, and violent shaking. The Captain surmised that they broke the sound barrier. 3,000 knots equates to over 3,000mph. The sound barrier (Mach 1) is about 767mph, and the captain would know that.
A Thing About Machines - S2-E4
Revealing mistake: When the car is approaching the pool to push the man into the water, the tires tracks are visible in the grass, showing that the car had already made that trip. Either tracks from an earlier take, or the scene was filmed and then played in reverse, to be safe for the actor.
The Odyssey of Flight 33 - S2-E18
Continuity mistake: When the jet is preparing to land in 1939 New York City, the view of the crew from the back of the cabin forward shows the airliner captain wearing his headphones, but the next instant close up of him shows him not wearing the headphones.
Nick of Time - S2-E7
Continuity mistake: Don Carter is holding a glass of water at the lunch counter. When the shot cuts to him and Pat, his hands are clasped together, empty.
Nick of Time - S2-E7
Continuity mistake: As Don and Pat leave the diner and another couple enters, there are two glasses of tea that have changed position on the table with the Mystic Seer, and two chairs have suddenly materialized at the booth they were using when the other couple arrive to use the Mystic Seer machine.
The Odyssey of Flight 33 - S2-E18
Continuity mistake: The radio operator's hand is gripping a bar behind the airliner captain, then in the next shot it's not.
The Arrival - S3-E2
Other mistake: As part of the story line, three men see different tail numbers on the plane. However, the first and third sets of numbers are printed on a big sticker, because the numbers are a different style than the second set. Also, they used two different planes. The second tail number is N67588, which should be on the bottom of the wing, but that number is N107932.
The Changing of the Guard - S3-E37
Continuity mistake: While at the window listening to the Christmas Carolers, the eyeglasses Professor Fowler is wearing disappear and reappear, depending on the camera angle.
The Odyssey of Flight 33 - S2-E18
Continuity mistake: There are three scenes of the jet flying above a thin layer of clouds. The same piece of footage is used each time.
Continuity mistake: Death has a bag full of purchases made from Lou. As they walk off, Death's bag disappears.
Continuity mistake: In the opening, Mr. Bookman has a toy replica of Robbie the Robot in his left hand in the close up, but a bottle in it a second later.
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.
Other mistake: When Mike first walks into the town he sees the ringing church bell then looks to his right. The camera acting as his POV pans from left to right but since he was already looking to his right then the camera would be facing the direction he just came from.
Continuity mistake: In the vault, the book Mr. Bemis puts down flips open a moment before the atomic blast. After the explosion, the book is closed again.
Will the Real Martian Please Stand Up - S2-E28
Revealing mistake: As the Venutian asks the Martian to play music, the edges of the fake skin around the third eye is visible.
The Mind and the Matter - S2-E27
Other mistake: In the office, Beechcroft's Mirror Image's hair is styled like his own, rather than reversed, as a reflection should be. In his bathroom, the hair in The Mirror reflection is correct.
