On a tangent more related to the original thread, I wonder what changes to the characters might have been deemed more appropriate in any sequels. Would Sulu or Uhura finally have got a love interest in a historical romp? It would seem a shame to send Uhura back to the sixties and not give her a couple scenes to do with civil rights. It looks like they were keen to focus more on the cultural aspects of the Klingons and this might have been fun. But the staging and plot sound very similar to CotEoF right down to the savage pirates in Ellison's original version. Did Roddenberry genuinely think he could persuade Ellison to get on board and let him use the Guardian again? I wonder if Grace Lee Whitney still had any currency with him given that they'd split up over her drug use in his house. He wrote a decent role for Rand in his original and I wonder if any part of his anger over the changes they made to the original was to do with the way she had been treated. Would Rand have got more than a cameo in a sequel I wonder. I think a story more tangential to the assassination might have been more likeable. A detective plot with teams consisting of the main characters tracking down the Klingon time team while Kirk romances Sister Melba Kreeler, played by Whoopi Goldberg.
