I am from Decades in the future (winky nudginess), so I'll post this on the 50th anniversary of the airdate....
The Time Tunnel
"One Way to the Moon"
Originally aired September 16, 1966
And TTT is streaming on ShoutFactory TV (free with ads), so I was able to watch early too.
I was wondering how they were going to handle the time paradox of the Tunnel team discovering Beard's future treason without altering the timeline. It turns out they didn't get the chance -- the episode avoided the whole issue of time paradoxes by keeping Beard's allegiance secret in the present (yet assuring that he got his comeuppance in the future).
But how could the wad of plastique that Brandon put under Ann's desktop have caused the back of the console to blow out without hurting Ann? And while Gen. Kirk ordering Ray to take Ann to safety is the kind of gender condescension you expect from the '60s (they would've called it chivalry), I have to wonder why the other one or two female technicians in the background weren't extended the same consideration.
I was wrong about the reuse of the Tic-Toc complex FX shots from the pilot -- we got a brief glimpse of the Tunnel Room matte painting here, plus another look at the reactor miniature and the stock shot of security running along the walkways. But the directing of the pursuit of Brandon through the complex spoils the illusion of the matte painting. The shots where he's hiding between the rings of the tunnel reveals that it's a forced-perspective set piece that tapers conically rather than extending far back cylindrically as in the painting. There's a low-angle shot on General Kirk and Ray that reveals the top of one of the side pillars that extend much higher in the painting. And the control complex is shown in the matte painting to be a platform on a column with a sheer drop on the other side of the outer barriers, but here we're clearly shown that there's just the stage floor on the other side of the barriers. Really frustrating.
Another odd discontinuity was the twosome referring to their project as "the Time Tunnel program" instead of "Project Tic-Toc." And what are the implications of the fact that their project is still unknown a decade in the future? Unfortunately, that will never be explored.
Of course, we also get plenty of stock footage from George Pal's
Destination Moon, and recycled spacesuits from same. Oddly, in the scene where Doug and Beard are fighting, Beard's air tank is a flat box with the air cylinders just painted on, whereas it's the genuine article in the later fight with Tony.
How quaint...a Mars mission with artificial gravity
Both the moment of free fall and the alleged rotational gravity make no sense, since both the sound effects and the exterior footage show that the rocket is still under thrust. Plus it's obviously not rotating in a way that could produce gravity. Plus the rocket in the liftoff footage is a completely different vehicle than the one in the stock
Destination Moon footage.
So...they heard a scream on the moon...from inside the rocket...when the guy who was screaming was in the lunar warehouse...and was wearing a spacesuit to boot...?
They heard Harlow's scream over the intercom. Just before, we saw a close-up of his hands turning the switches on the waist unit, and we later saw Doug operating the same switches to activate his radio to call Tony. So Harlow must've turned on his radio to call for help, but been unable to.
This is the first episode I've seen...from the way that the spacesuits disappear when the the guys go back into the timestream, I take it that they never get to change their clothes?
The Time Tunnel depended on stock footage -- both the stock footage from old movies that most of the episodes were built around, and the recycled footage of Doug and Tony tumbling through the timestream from the pilot. So no matter what wardrobe changes or damage they went through in the episode, they always magically changed back into Doug's 1912-style gray suit and Tony's 1968-style green sweater when they were swept back into the timestream.
