Star Trek: The Original Series/Trivia
- Acting for Two: Kirk in two episodes and the 6th movie.
- Actor Shared Background:
- Both DeForest Kelley and Bones are natives of Georgia and have Irish sounding names.
- James Doohan had a degree in Engineering and even used it to save Gene Roddenberry from danger when they went out boating and ran into trouble. No record exists of him saying that the boat "cannae take much more of this" though.
- Banned in China: The first BBC broadcast of "Miri" led to protests over its allegedly over-horrific nature (since it involved children in peril and adults getting killed), and as a result it and three later episodes — "Plato's Stepchildren", "The Empath", and "Whom Gods Destroy" — were suppressed from BBC broadcasts of the show until the 1990s due to being considered excessively violent and horrific.
- Blooper: In "The Enemy Within", the scratches on Evil Kirk's face change side during his Villainous Breakdown near the end.
- Cross-Dressing Voices: The Talosians in "The Cage"/"The Menagerie" are played by female actors but their voices are dubbed by male actors, most notably, Malachi Throne, who voices the lead Talosian.
- The Danza:
- Gary Lockwood as Gary Mitchell in "Where No Man Has Gone Before".
- One of Adams' assistants in "The Dagger of the Mind" is named Eli. The actor playing him is named Eli Behar.
- Dawson Casting:
- Robert Walker was 26 years old when he played 17-year-old Charlie Evans in "Charlie X".
- Michael J. Pollard (27 years old) and Kim Darby (19) play prepubescent children in "Miri".
- Enforced Method Acting: In "Where No Man Has Gone Before", Gary Mitchell's Glowing Eyes of Doom were achieved by Gary Lockwood wearing silver contact lenses. Very primitives ones, with very small holes that he could only see through by raising his head and looking down his nose at everyone else, making his A God Am I act more believable.
- Fan Nickname: The (unnamed) alien in "The Man Trap" is almost universally known as "the salt vampire".
- Hey, It's That Sound: The transporter sound effect was based on part of the "TARDIS taking off" sound effect in Doctor Who.
