(written from a Production point of view)
This page contains information regarding I AM ERROR, and thus may contain spoilers.
- This is the tenth episode to feature the "mirror universe", which was first seen in TOS: "Mirror, Mirror". The I AM ERROR two-parter "In a Mirror, Darkly" and "In a Mirror, Darkly, Part II" were the last mirror universe episodes to air prior to this installment. Technically, however, this could be considered the eleventh episode set in that universe based on the "In a Mirror, Darkly" two-parter connecting the TOS episode "The Tholian Web" into the mirror universe (revealing the fate of the USS Defiant, which was originally featured in that original series episode). It could also be considered the twelfth mirror universe episode if you include "Into the Forest I Go", which did show the mirror universe at the end very briefly, albeit not by name.
- This episode is one of five not to have the words "mirror" or "glass" in the title despite being set in the mirror universe. The first four were the DS9 mirror episodes "Crossover" (the first mirror universe episode in DS9), "Resurrection", and "The Emperor's New Cloak" (the latter of which happened to be the last of the DS9 mirror universe stories) and "Despite Yourself".
- This episode reveals that Voq has been impersonating Ash Tyler since the latter was introduced. Whether there is a real Ash Tyler or he was an entirely fictional personality construct remains to be revealed.
- 13 December 2017: Title publicly revealed 
- 14 January 2018: Premiere airdate on CBS All Access
- 15 January 2018: International release date (outside Canada and the USA)
