Land of the Giants

Allegedly midway through the episode the producers noticed that Valerie was showing a bit too much cleavage. They put a kind of "cleavage" patch on, but because the scenes weren't filmed in sequence, it appears and disappears several times. She starts with no patch, then it appears when she gets dumped in the box, then it disappears when she and Fitz are put in the plane. Then it reappears again when she appears in the graveyard, and disappears after she wakes up from being stunned, and remains gone for the rest of the episode.

Supposedly alien planet: The giants use the cliche "curiosity killed the cat"

Steve and Dan's hairstyles are noticeably different in the clips used from the pilot episode.

Trivia: The original ship that was to make the trip was called the Shamrock.

Instead of acting like a jerk and stealing their STM, why doesn't Steve just ask Thorg and Berna to teleport everyone back to Earth in the present? All they ever say is that they can't alter "history". There seems to be no reason they can't alter the "present". But if the "present" is their history, then they kill a giant guard which presumably violates their mandate too.

So Berna and Thorg aren't Earthlings, and they're not giants. Who are they?

Miss Collier seems oddly unconcerned about the fact that Steve threw a chair through her window!

Presumably the original timeline remained unchanged. But wouldn't anyone have ever mentioned how Steve and Dan prophesied the crash in the new timeline? Or does that just not make much difference?

The temporal "physics" aren't clear here. In the original timeline, what occurred that forced the airport to use Spindrift instead of Shamrock? Here it is implied that Steve's own intervention triggered the use of Spindrift...but that didn't occur originally. And so on.

Steve says he is going to sabotage all the ships: it isn't clear why he ignores/forgets the Spindrift.

So what happened to the original Dan and Steve? Presumably they were "displaced" in some manner, but this isn't made very clear, and it doesn't seem like the same rules apply to Thorg and Berna.

Dan takes forever to get involved in the fight when Steve attacks Thorg at the airport.

After the giant and his dog spot Thorg and the dog picks him up, Thorg is teleported back to the same spot where he was picked up the first time. Why can't the giant see him when he's in the same place as before?

Steve identifies their date of departure as September 25, 1983. In the pilot episode, the date is noted on-screen as June 16, 1983.

Supposedly alien planet: human names again

Since Brady doesn't seem to do anything about Goalby and Lisa, why can't the Earthlings use Goalby as a continuing ally: he certainly seems helpful enough.

Supposedly alien planet: Cole Porter lyrics! The Giants don't seem surprised or puzzled at the existence of this song, so presumably they have Cole Porter, Judy Garland, and the 1948 movie The Pirate on their planet (see Cultural References below).

Supposedly alien planet: circus acts and cliches

It's not clear why Sandra Giles receives an opening credit, since she only has 2-3 lines of dialogue.

It is never explained why Bobo is acting in such a hostile manner. It is implied Brady mistreated him in some manner, but this is never stated or shown on-screen.
