So who the heck was the overalled guy at the beginning? He's not dressed like anyone else in town and we never see him again.
Not surprisingly, most of the people who are frozen "like stone" tend to sway and twitch noticeably.
The stock footage of attacking locals is taken from a wide variety of sources and their costumes differ widely from shot to shot.
Apparently the time tunnel can now send people to exact space/time coordinates, yet no one thinks to send Tony and Doug to the exact coordinates of the present-day tunnel complex.
For some reason the alien makes a distinction between "sun" and "Canopis," but muddles his own argument. He says his people are not powered by "sunlight" but by "Canopian-light." But "sun" is a general term (like "moon") as opposed to a specific name ("Sol"). So "sunlight" is correct usage of the term on an alien planet.
These people immediately shut down once their sun disappears. That means they are solar-powered with no capacity for energy storage. This doesn't make sense. If they photosynthesize like plants, surely they'd store energy for use during nighttime. Just as humans store energy for times they aren't eating. Without power sources, these people can't even go into a poorly lit room.
Don't they have replacement parts in the future? The Curator seems to assume the Time Tunnel staff can't replace the time/space converter and he's stymied them by taking the part.
Why does the alien Canopis computer use "Anno Domini" (A.D.) when providing dates for its records?
Kirk says it's his job to protect the integrity of the timeline. However he seemed all too willing to send a machine gun to Troy ("Revenge of the Gods") and percussion detonators to Mongolia ("Attack of the Barbarians").
Merlin reverses time for Arthur to revive him, but Arthur remembers the whole incident. Wouldn't his memories have been reversed as well?
Supposedly the Tunnel locked onto Machiavelli because of his similarity to Doug's "pattern." Apparently Doug's pattern can also encompass a very large dog, plus a sizable trunk full of stuff.
So Machiavelli can't be killed because he's displaced in time and his death would change history? Shouldn't the same apply to Doug and Tony, in their future travels if nothing else?
When Doug first meets up with Tony in 1 million BC, his shirt is clearly torn and blackened. However, by the time he puts his jacket back on, the shirt is still torn, but is nowhere near as dirty as it was.
We are told that the time travellers have been whisked back one million years into the past - where they encounter dinosaurs (actually stock footage modern lizards masquerading as dinosaurs from the Irwin Allen "Lost World" movie). However, the last dinosaurs diappeared 65 million years ago.
Watch the guy in the yellow suit with a clipboard as Niman comes running out shooting. Everyone else ducks and cowers--he just kind of tries to blend into the console.
Kirk says that the pirate can't be killed after he's brought through the tunnel. If that's true, then Tony and Doug should be invulnerable outside of their time as well, which clearly isn't the case.
This episode may be the first when it is really noticeable, but several times in the series when the guys "land" they are obviously hanging from moving cables and letting go to create the effect of momentum. In previous episodes it looked as if they were just being thrown, but the shadows of the cables are clearly visible here.
Probably not the first time this has happened, but as Berkhart walks into the tunnel, you can see his shadow on the "infinite" matte shot directly in front of him.
Right after Tony tells the young chief "You have no stomach for revenge..." etc., we cut to a scene of Doug running up, saying "Go back down the trail..." During this shot, the zipper going down the left shoulder of Tony's turtleneck (which James Darren had the wardrobe people install so that he could let his neck breath every once in awhile) is left open!
When Doug throws the torch down on the line of gunpowder, it clearly lands in the middle of the line, but the line still ignites from the very end.
