Did You Know?


The Star Trek (1966) original series episodes Star Trek: Charlie X (1966) and Star Trek: A Piece of the Action (1968) were originally considered for reprisal before settling on Star Trek: The Trouble with Tribbles (1967). Coincidentally, while the producers were at a pizza parlor discussing the episode, Charlie Brill happened to be eating there as well. Ira Steven Behr recognized Brill and offered him the chance to reprise his role. See more »


Chief O'Brien's hairstyle reverts back to his "normal" 24th Century hairstyle once He and Dr. Bashir beam over to the K7 space station from the Enterprise. Moments earlier, his hairstyle reflected the hairstyle (combover with part) as worn by the 23rd century human male crew members. See more »

This episode of "Star Trek: Deep Space 9" is obviously a labor of love that was created to coincide with the 30th anniversary of the franchise. However, instead of just a special episode, the folks who made this went all out and really worked hard to create a treat for the Trekkers and Trekkies out there. How? Using modern technology, they formulated a good plot which allowed the series regulars on the show to impose themselves into one of the iconic episodes of the original series. So, using a combination of cleaned up original footage from "Star Trek: The Trouble With Tribbles", old-style cameras and new computer technology they were able to make an immensely clever episode.

It all begins with some temporal agents visiting DS9. It seems that the crew members recently went back in time and the agents were there to make sure history was not changed and to punish everyone unless there was a darned good reason to make such a journey. What is the reason? A Klingon agent, Mr. Darvin, has arrived on DS9 and the crew later discover he's the same agent discovered at the end of "The Trouble With Tribbles"--and he soon jumps back in time to undo his mistake and change history.

There is so much to love about this episode. It was NOT hastily tossed together and it's fun seeing the new DS9 folks acting like fanboys and fangirls when they see their old heroes, such as James Kirk. Cute, fun and enjoyable even if you aren't familiar with the old series.
