Hmm.. what would I like to see... or what would have actually happened?
Planet of the Titans does make for an interesting idea and it does seem to fit in just fine with the TOS style.
The film involved
Starfleet competing with the
Klingons for claim to the supposed homeworld of the mythical Titans, a technologically-advanced race long thought extinct. As the planet is pulled into a
black hole, the
USS Enterprise must also face off against the Cygnans, the alien race responsible for the Titans' disappearance. Ultimately, Captain
Kirk is forced to take the
Enterprise into the black hole to defeat the Cygnans, a decision that sends the starship and its crew backwards in time thousands of years and into orbit around
Earth. After introducing fire to the primitive
Humans living at the time, Kirk and his crew are revealed to be the legendary Titans. (
The Making of Star Trek: The Motion Picture)
The time travel element might be a bit much and could bog the movie down at the end. That might need reworked a bit.
Roddenberry is a bit of a one-trick pony. Once he gets an idea, he mines it to death. In the early 70s after Star Trek he wrote 3 sci-fi movies or pilots that ultimately failed -
Genesis II,
Planet Earth and
Strange New World. All 3 depicted a civilization on Earth rising from the ashes of a nuclear holocaust. So, perhaps a TOS movie wold have fit that mold - The
Enterprise encounters yet another parallel Earth. This particular planet is recovering from a nuclear war. An evil totalitarian government is battling for control of the planet. The crew of the Enterprise (are forced to?) help the more benevolent Pax civilization defeat the totalitarian regime and establish a utopian government based upon pacifism, science and egalitarian progressive concept modeled after the United Federation of Planets. So, we're talking a remake of "The Omega Glory" without all the Yang and Coms nonsense and, instead of a deranged Starfleet Captain we have a deranged native of the planet (or we have a deranged Starfleet Captain after all and he's the one that helped rebuild the totalitarian regime years ago and the
Enterprise was sent to investigate his disappearance. We're now crossing "The Omega Glory" with "Patterns of Force").
Yep, I think that's itl A big budget movie that remakes and combines "The Omega Glory" with "Patterns of Force." Instead of the Yangs vs the Coms we have the peace loving Pax vs. a re-imagined Soviet Union.
