Trivia: Mudd's record notes under Sentences: Psychiatric Treatment... Effectiveness Disputed. His Future Police Record Code is X731248.
When Spock orders Farrell to set a court for Rigel 12, Farrell's insignia is missing.
When the women beam on board, the brunette is in the back. then there's a reaction shot of the three women standing abreast. Then in the next shot the brunette is in the back of the transporter chamber again.
Trivia: According to Scotty, the Enterprise is almost a million gross tons.
During the hearing, the picture of Harry Mudd on the desktop viewscreen is reversed. Harry's earring is in his left ear, but in the photograph, it is in his right ear.
Since this episode is set fairly early in the first season and the backstories are still a little inconsistent, the Enterprise is being powered by lithium instead of dilithium and Harry Mudd calls Spock "Vulcanian" instead of "Vulcan."
At one point Kirk returns his quarters to find Eve laying on his bed. Eve says something about she got tired wandering the ship and ducked into the closest room. You would expect crew's quarters to be off limits to those other than the ones assigned to them, or maintenance/etc. people as needed. Even if the general crew's quarters weren't secured surely the captain's quarters would be. How did Eve get in?
Exactly how and when did Kirk learn of the girls using the Venus drug? Before Eve fled into the storm Harry was pretty much running the show and hadn't told any of the crew. Harry apparently returned to the ship to help look for Eve (or to watch to make sure they did the search correctly) but he didn't appear to be in custody. The next time we see Kirk and Harry is in Childress's quarters after Eve's Venus pill has worn off. Somehow in this time Kirk managed to find out that Harry was using an illegal drug (something Harry wouldn't have admitted to voluntarily) and replaced it with colored gelatin. Also in this time he has gotten Harry to cooperate with him in pretending to give Eve a placebo.
Even with the power on emergency batteries and no lithium crystals left the crew continues to use the transporter to get back and forth between the surface and the ship. This is likely because the writers hadn't dreamed up the ship having shuttle pods yet.
Although Harry and the girls are beamed over just in time before their ship explodes, their belongings seem too have made it as well. Harry searches through several drawers of clothes while hunting for the Venus pills as well as picking up and looking in a knick-nack type object.
There is major confusion about when power will run out and when the ship will crash. The ship can continue in a normal, non-decaying orbit as long as it has power to make course adjustments. Once the power is out the orbit will start to decay. Likely the Enterprise had another 2-3 days before it would crash. However, life support would fail before the ship crashed, but there would be enough breathable atmosphere on the ship to last at least for many hours if not a day or more.
Right before Ruth comes into sick bay to visit McCoy and find out the health condition of the miners, McCoy switches off the diagnostic panel. Yet when Ruth walks by and stands in front of it the two middle lights start flashing erratically. No wonder he was surprised!
In the scene in which Leo Walsh/Harry Mudd and his "cargo" are under guard in the conference room and he is briefing the women on how to handle the impending interrogation, he calls one of them "Rose". The three women are named Magda Kovas, Eve McHuron and Ruth Bonaventure.
Also on the McCoy uniform business. The close up of him in his medical uniform is also used later when one of the women (the one dressed in green) enters the sickbay, that close-up is also used there. Presumably to save money from either another episode or just using the same close-up twice.
Kirk's says that it is Stardate 1329.8 in his opening log entry when the ship is in pursuit of Mudd's vessel. But after Mudd and the women have been brought aboard, Kirk's next log entry says that it is Stardate 1329.1.
Why doesn't Uhura or anyone at the communication board pick up that Harry communicates with the miners? It's later determined that Enterprise crew can detect someone sending transmissions off the ship.
The Venus drug not only rejuvenates, it supplies makeup and false eyelashes.
When Harry gives the women a supply of the Venus drug, the box he takes it out of does/doesn't/does have a lid in successive shots.
Kirk tells Spock at the end that he's coming back with Harry and the crystals they desperately need...then he walks out with Harry and leaves the crystals behind.
Kirk confines Mudd to his quarters with a security guard, but later when Kirk meets with Childress, Harry just wanders in. What happened to the guard?
While Mudd discusses his plan to marry off his Women to the miners in the briefing room and get the upper hand on Kirk, the two security guards stand at the door but apparently don't hear a single thing despite Harry's loud boasting.
As Mr. Scott beams the three women aboard, Mr. Spock and Dr. McCoy are with him in the transporter room. When they are beamed aboard, the three men begin to stare. The camera pulls in tight on each officer's reactions. When they shoot a close up of McCoy, we find that his uniform has changed to his sickbay medical frock and the wall of Sickbay is behind him. Then, when they pull back out and show all three men again, McCoy is back in standard uniform.
Spock: I'm happy the affair is over. A most annoying emotional episode.
McCoy: Smack right in the old heart. Oh, I'm sorry. In your case, it would be about here.
Spock: The fact that my internal arrangement differs from yours, Doctor, pleases me no end.
Harry Mudd: You're a hard-nosed one, Captain.
Kirk: And you're a liar. I think we both understand each other.
Kirk: Computer, go to sensor probe. Any unusual readings?
Computer: No decipherable reading on females. However, unusual reading on male board members. Detecting high respiration patterns, perspiration rates up, heartbeat rapid, blood pressure higher than normal.
Kirk: Uh, that's sufficient. Strike that from the record, Mr. Spock.
Ben: I guess I'm supposed to sit, taste, and roll my eyes. "Ooh, female cooking again." I've tasted better, by my own hand.
Eve: You're tasting some of it. I couldn't scrape your leavings out of that pan.
Kirk: But I will appear as a character witness at your trial... if you think that'll help.
Mudd: They'll throw away the key.
Kirk: (to Eve and to Ben Childress) There's only one kind of woman.
Mudd: Or man for that matter.
Kirk: You either believe in yourself, or you don't.
Eve: Oh, that sound of male ego. You travel halfway across the galaxy and it's still the same song.
Mudd: Men will always be men -- no matter where they are.
Leonard Nimoy's "Also Starring" credit is missing from the opening titles.
This episode depicts the Enterprisess power source as "lithium" crystals. The prefix "di" was added later as lithium is a real element and a metal and does not occur as crystals.
This episode was a potential pilot for Star Trek.
Gene Dynarski also appeared as Krodak in "The Mark of Gideon" and as Cmdr. Orfil Quinteros in the TNG episode "11001001".
Uhura wears a gold uniform in this episode.
