Assignment: Earth

(Star Trek story #55 in production order)
  • story by Gene Roddenberry and Art Wallace
  • teleplay by Art Wallace
  • directed by Marc Daniels

Assignment: Earth

Star Trek saves its only second season foray into the world of time travel proper for the very end of its run, which turns out to be an exceedingly bland run-of-the-mill exercise that re-hashes its usual petrified take on the subject. The opening, and indeed many of the challenges of the story, are extremely reminiscent of "Tomorrow is Yesterday" (Star Trek production #21), with talk of the "lightspeed breakaway factor" bringing the Enterprise and crew to then-present-day 1968 - although this time on purpose and with intention to study the time without allowing themselves to be detected. No sooner do they record this in the log than an adventure slams into them. With their strict restrictive fear of altering anything, you have to wonder why they bothered to tempt fate in the first place.

What is perhaps more interesting is revealed in Herb Solow and Robert Justman's "Inside Star Trek" book and audio cassettes: that this episode is a thinly disguised backdoor pilot for a proposed TV series about Robert Lansing's Gary Seven alien agent, saving humanity each week in James Bond style with the aid of his Earthly assistant Roberta Lincoln (Teri Garr) and his mysterious cat-woman companion Isis. That series might even have gone somewhere, if only this "pilot" episode wasn't such a clunker.

The biggest flaw in the episode is the lack of a proper, tangible, externalized antagonistic force to drive the conflict in the plot. All of the major characters belong to either Star Trek's cast of heroic regulars, or the proposed new cast of Gary Seven's heroes. The writers attempt to generate most of the story's conflict artificially between these two groups, while any roles outside of these groups remain uninteresting bit parts. There are major motivational problems as well, because Gary Seven is the only character who knows what's going on, and he keeps too much information to himself until the very end. All the other characters are left in the dark, with our Star Trek regulars forced to doubt their every possibility for a move, spending all their time either second guessing themselves cluelessly, or standing around in some form of captivity waiting for something to happen. For a story that's meant to double as the 55th of Star Trek, and as the 1st for "The Adventures of Gary Seven", the story really doesn't do justice to either series or either set of characters. The audience is left with no-one to root for, and nothing to get emotionally invested in.

There is some fun to be had with this episode. Teri Garr's bubbly presence lifts the episode up a notch, and is one of the story's highlights. Her costume seems to be more suited for a quietly posing model though, and looks a bit out of place when she starts jumping around the set like a monkey. The episode also uses a lot of footage of a rocket ready for launch, which is the kind of thing that can easily drone on too long and be a bore. "Assignment: Earth" is at least successful in combatting this by having Scotty encourage the audience to try to spot Gary Seven somewhere in there with him, elevating our interest in such footage enormously. Nice one.

When all is said and done, this Star Trek episode actually does keep its nose clean in terms of what actually happens with regard to time travel. Nothing "changes" magically, history proceeds logically, no conundrums bugger up the writing. The belief in such possibilities has merely rendered the characters extremely impotent and boring today. Because any time-travel no-no's are limited to beliefs inside the characters, this is actually the best of the three full-length time travel stories produced on Star Trek so far. Yet it still isn't a winner by any stretch of the imagination.

It is interesting to ponder Gary Seven's actual take on time travel though. He appears to have some knowledge of future history, but he only verbalizes the threat of changing history when he realizes who the Enterprise crew are, as though he is tailoring his remarks to fit in with what he knows their belief systems would be. What does he himself really believe? Perhaps this is still officially up in the air, although it's hard to think that the Star Trek writers who penned this episode actually have anything more metaphysically correct in mind. Had "The Adventures of Gary Seven" become a series, it could have safely stayed away from any time travel, as Gary only travels across space, and it would probably have turned out to be much more dramatic, exciting, and interesting than this poorly designed pilot could show.


Best Story:

  1. The Doomsday Machine
  2. The Trouble With Tribbles
  3. Journey to Babel
  4. Mirror, Mirror
  5. Who Mourns For Adonais?
  6. The Ultimate Computer (the most organic and potent of all the Kirk-vs-Computer conflicts on Trek)

  7. A Piece of the Action
  8. Obsession (solidly plotted, but a bit slow)
  9. Amok Time
  10. The Immunity Syndrome
  11. The Deadly Years (the real fun is watching Shatner and Kelley chew the scenery in this one)

  12. By Any Other Name
  13. The Changeling
  14. Friday's Child (although not a very effective ending)
  15. Metamorphosis

  16. Assignment: Earth
  17. I, Mudd (VERY goofy, and too loose a grasp of AI machine logic)
  18. Return to Tomorrow (some good bits for sure, but quite wet, slow, and just not very exciting. How can the aliens do all that, and not build more sensitive androids for themselves? Why not build them millions of years ago?)
  19. Catspaw
  20. The Apple (characters not very interesting in this one)
  21. Wolf in the Fold (well made, but not my style of content)
  22. The Omega Glory
  23. Patterns of Force

  24. Bread and Circuses (overriding feeling of unpleasantness / uselessness)
  25. The Gamesters of Triskelion
  26. A Private Little War

Best Music:

  1. Fred Steiner: Who Mourns For Adonais?
  2. Gerald Fried: Friday's Child
  3. Sol Kaplan: The Doomsday Machine
  4. Gerald Fried: Amok Time

  5. Gerald Fried: Catspaw

  9. Alexander Courage: New Compositions for Season Two Library
  10. George Duning: Return to Tomorrow

  11. Samuel Matlovsky: I, Mudd
  12. Fred Steiner: Mirror, Mirror (really, is anything new here?)
  13. George Duning: Patterns of Force marches
  14. Fred Steiner: The Omega Glory

Star Trek Season Two "Purist" Standard DVD Box Set:

Watch the legend continue to develop through its prime. Set contains all 26 episodes from the second season in their original wacky broadcast order, plus new bonus features.

As someone interested in researching how the episodes actually looked and sounded originally, and when and exactly how certain musical cues first debuted, this was the DVD set for me, and it remains the most untampered-with full-season collection of Star Trek out there. Unique extras include pure text commentaries on select episodes. Sadly, these sets are starting to become rare, and prices are now rising as these become collectors' items....

The Original Series Remastered Sets

The re-mastered Star Trek set for season two, like that of season three, seems destined to be obsolete in very short order. Its content is easily surpassed by the more respectful presentation on Blu-ray, and unlike the "purist" DVD release listed above, appears to have none of its own exclusive content. Add to that the very gimmicky, awkward packaging that is prone to damage both during shipping and with light usage, and I'd have to recommend that all devoted Trekkers should consider other options for their ideal TOS season two product.

Season Two - Blu Ray

  26 episodes @ 51 minutes
Star Trek sets are now available on Blu Ray. Picture and sound quality restoration has gone up yet another notch since the remastered version, as have the liberties taken with "upgrading" the episodes. Once again, even newer CGI effects and optical shots have replaced many space scenes, matte paintings, and phaser effects.... but this time the upgrades have the same respect and user-functionality applied to select Doctor Who DVD releases since 2002, as the CGI effects can now be turned off to see the original effects. Good show. It seems that the music has still been tampered with too much for my liking though.
