The Warrior's Anthem first heard in the CD-ROM adventure Star Trek: Klingon (which also featured J.G. Hertzler, though not as Martok) enters Star Trek canon in this episode.
In the documentary What We Left Behind (2019) Michael Dorn revealed that this episode and Once More Unto the Breach (1998) were his two favorite episodes out of all of his appearances, both on Deep Space 9 and TNG. He called both episodes "Shakespearean" in their scope.
This episode was directed by LeVar Burton, who played Geordi La Forge in Star Trek: The Next Generation (1987).
This is the second episode of Star Trek to be set primarily aboard a Klingon ship, after TNG: "A Matter of Honor", eight years earlier.
The IKS Rotarran makes its first appearance in this episode. The Rotarran reappeared as Martok's command ship in "Sons and Daughters" before being replaced by the IKS Ch'Tang in "Once More Unto the Breach". The Rotarran reappears In "Tacking Into the Wind".
