Star Trek: Enterprise Season 5
Enterprise joins Star Trek the Original Series as the only Star Trek shows to ever be cancelled. Despite being in such prestigious company, TOS kicked off 47 years of the franchise while Enterprise nearly killed it. While the program had ironically enough, seemed to be tapping into its potential as a prequel to TOS, it could not generate sufficient ratings to justify its existence. Show Runner Manny Cottos vision of Season 5 however offered an intriguing and even deeper look into the early years of the United Federation of Planets. Among the stories that never made it to the screen:
The Return of Captain Kirk William Shatner had pitched a story that involved Enterprise stumbling upon a time and dimensionally displaced Mirror Universe Tiberius Kirk. During the course of the episode it would be revealed that there was no Mirror Universe for him to return to as it had not been created yet. This would lead to Archer working with Kirk to determine where and when the Mirror Universe was formed and making sure it comes into existence. Another proposed idea saw William Shatner playing Enterprises chef, a Kirk look-alike dragged into the Temporal Cold War and needed to fill in for Kirk at a pivotal point in history. Unable to reach an agreement with Shatner, both stories ended up on the rubbish heap.
The Borg BeginsGoing to the well one more time with the overused and watered down Borg was on the cards. This story would have seen the secret origin of the Borg Queen with Alice Krige returning to Star Trek as a Starfleet Medical Officer assimilated by the Borg from Season 2s Regeneration
Crossover with Doctor Who While later depicted in comic form, two of science fictions greatest and longest lived franchises had never teamed up before. Russell T. Davis former showrunner for Doctor Who has confirmed that had Enterprise not been cancelled, he would have been looking to bring the Tardis into Federation Space.
The First Live Action Appearance Of The Kzinti Donated by author Larry Niven to the universe of Star Trek via the Animated Series, the feline enemies of the Federation had never made it to the live action big or little screens. A script entitled Kilkenny Cats, writer Jimmy Diggs said ... Captain Archer encounters the Kzinti after an 80 year period of no contact with the Federation. Larry Niven loved it, D.C. Fontana and Andre Bormanis both story edited the script and signed on the final draft. This story may be resurrected however as part of the fan produced Star Trek Phase II project.
