Same car scene in two episodes

Also, if you notice when they spray paint the X on the car roof, it's kind of thin and shakily done. Later when they show the car on the road, the X is perfectly formed running from corner to corner of the roof, and substantially thicker.

He who fights and runs away, lives to run away again!

I noticed that they re-used the flying sub scenes a lot of times. I found out that Richard Basehart got sick during the making of the "The Monster's Web" episode. Did something happened to Terry Becker? He's not in some of the episodes.

The limo used in the VTTBOTS pilot (and reused in "The X-Factor" espisode) was a Chrysler Imperial. That is the same type of car that was modified to create the "Black Beauty" in the classic Bruce Lee "Green Hornet" series of 1966, and also in the current-running "Green Hornet" film starring Seth Rogen (a 1965 model).

I remember when I first saw the footage in “The X Factor”, I recognized it from the pilot and wondered how they got color footage from a black & white episode. It wasn’t until later that I found out the pilot was shot in color (which is common knowledge now).

But the reuse of footage was not really a surprise. Irwin Allen often reused footage in VOYAGE. For example he recycled footage from “The Mechanical Man” in both “Rescue” and “Terrible Leprechaun.” The footage from “Jonah and the Whale” was reused in “Shape of Doom” and some other footage in “Shape” came from “The Ghost of Moby Dick.” And of course, footage from his movie THE LOST WORLD showed up in “Turn Back the Clock”, “Terror on Dinosaur Island” “Night of Terror” and “A Time to Die.” Probably the most blatant example is the episode “No Escape from Death” which was cobbled together from segments of “Submarine Sunk Here”, “Hail to the Chief” and (I think) “The Creature.” There was perhaps ten minutes of new footage in it all together. The man really knew how to recycle!
