From Letters of Note: an exchange between Isaac Asimov and Gene Roddenberry that began when Asimov wrote an item for TV Guide criticizing inaccuracies in televised science fiction.
The first letter in the series, from Roddenberry to Asimov, contained the following:
In the specific comment you made about Star Trek, the mysterious cloud being “one-half light-year outside the Galaxy,” I agree certainly that this was stated badly, but on the other hand, it got past a Rand Corporation physicist who is hired by us to review all of our stories and scripts, and further, got past Kellum deForest Research who is also hired to do the same job.
What jumped out at me there was the name “Kellum deForest”. I thought at first it had to be an inside joke of some sort, but it turns out there really was a film researcher by that name (well, almost — it’s correctly spelled “Kellam”). Why an inside joke? Because, of course, the actor who played Leonard “Bones” McCoy on Star Trek had the unusual name DeForest Kelley. It seemed too much of a coincidence to be true, but apparently it was.
Anyway, have a look here.
