Who Actually Deserves the Credit:
It's a sad fact of life: There's only enough room in the human heart for one Gene at a time. That's why you probably haven't heard of Gene Coon. He served as producer for the original Star Trek in its first and second seasons, wrote eight of those episodes, and then wrote another four for the third season. Among his contributions to the franchise are the Klingons, the Federation, Starfleet Command and the Prime Directive. He also wrote the episodes with Gorn (the lizard man), Khan, those half-black/half-white aliens who taught us that space racism is bad (again) and the inventor of the warp drive. Basically, if there's something you remember from old Star Trek that's not Uhura's miniskirt or Kirk's dropkick, Coon did it.
"But the two-handed punch? That was all Shatner."
William Shatner and Leonard Nimoy have both called Coon the unsung hero of Star Trek. And without his over-arching structure and influence, Star Trek probably would've just been a show about unitard-wearing swingers screwing aliens across the galaxy. Which is ... kind of awesome, actually. We call dibs on the rights.
We shall call it: Sexual Predators Lost in Space.
We wouldn't even have to change the leading man.
