This was the first episode of Star Trek: New Voyages to be filmed in 16x9 widescreen. It was also the first episode of the series to have its own musical score.
A brand new opening titles sequence was designed for this episode.
At the end of the episode a "Next Voyage" section was included featuring a trailer for "World Enough and Time".
"To Serve All My Days" sparked some controversy over its apparent violation of official Star Trekcanon. In response to the uproar, James Cawley posted this on the STNV discussion forum:
"New Voyages is STRICTLY adhering to "CANON" Trek, which is the episodes that have been produced by Paramount for the last 40 years and that includes the animated series (at least in our book!)
I know that some are put off or confused by the ending of TSAMD, but, do you honestly think, some very serious conversations did not take place before we filmed it? I would ask all of you to take a deep breath and think........ Was Scotty killed in "The Changeling"? Did Spock remain dead in the features? Did the Enterprise get destroyed and not rebuilt in the features? Were these things wrapped up? I set out to tell a tale that would be meaningful, and thought provoking without diluting the ending. It has sparked some genuine debate, and gotten a few very riled up. I have accomplished what Gene Roddenberry loved to do. We made you think. We provoked a reaction. That is MORE than anything that Canon Trek has done in several years!
Now that I have you thinking let me say this. Chekov IS in the next episode and I am sure that somewhere in that one hour if you pay attention, you will smile. After all, I AM THE BIGGEST FANBOY OF THEM ALL!"
His claim that Chekov will appear in "World Enough and Time" is further clarified by his (brief) appearance in the "Next Voyage" section included at the end of TSAMD.
This episode and its successor are available as a Rifftrax commentary under the Rifftrax Presents line of commentaries.
