I distinctly remember reading once upon a time (around the time of its release, actually) that Meyer's original title for Star Trek II was
Star Trek II: The Undiscovered Country. Little short on ideas, Nicholas?
Man, some people just never can let an idea go.
If something sounds good and appropriate, hell yeah hang onto it. I came up with the title CRITICAL ORBIT when I was 15 and trying to make a medium sized space movie in Super8. A couple years later, when Disney was publicly seeking alternative titles to THE BLACK HOLE, I sent CRITICAL ORBIT to them (I still think they should have used it.)
I made a totally different Space film in the early 80s called CRITICAL ORBIT, but a cast member died and another disappeared so I couldn't finish it. In the LATE 80s I rewrote it as a full-length script, similar universe but with way too much Heinlein-esque practicalmindedness.
When I pitched to TNG at the end of 1990 one of my pitches (which still had a morsel from the early 80s version in it) was also CRITICAL ORBIT.
Then in the early 90s I made it very very different, about themes and 'tudes that really interested me, first as a feature script and then as a whole series of story ideas for CRITICAL ORBIT as a TV series, called CRITICAL ORBITS. (this is around the time I noticed that Kirk actually uses the phrase 'critical orbit' in THE NAKED TIME, which kind of took the wind out of my sails for a bit.)
I still mess with those early 90s versions from time to time ... it really REALLY seems like FIREFLY, but with slightly less vivid characters and much much better science. Had a general outline for whole series, one that would have had a clever little thing ... various guest stars would be filmed seated in something like a Capt's chair in a bit that didn't go into the episode. For the last episode, when things have changed enormously for the characters and they aren't privateers anymore, you were going to see a huge fleet of ships deploying for an extended mission, and see that leftover extra shot for each of these guest stars, who were each commanding one of the ships in this fleet, which is ... man, I gotta sit down and reread all this, I'm getting jazzed thinking about it.
(Now that I wrote that out, I'm wondering if the title is what has jinxed these projects. Had the same name for the main character throughout all this too, except for the early 80s version.)
