When Ares offers Xena any warrior from history, Xena mentions Agamemnon, Hector and Achilles and says that they are all "long gone", but a whole season later Xena and Gabrielle would walk in on the Trojan War, the conflict that Agamemnon spearheaded and Hector and Achilles died at the end of. Furthermore, in mythology, Hercules was supposed to have died long before the conflict began.
Kevin Smith makes his debut as Ares, God of War. The character had appeared often in the first season of Hercules: The Legendary Journeys (1995), at times in non-corporeal form and at other times in possessed bodies "borrowed" from other people. Smith continued playing Ares in both series as well as the short-lived prequel Young Hercules (1998).
Kevin Smith's beard was a fake which was glued on, and he said that he couldn't move his face much for fear of it falling off.
This is the first episode in which Xena wears her scabbard on her back. Prior to this, her sword was sheathed on her left hip.
Xena displays a form of superhuman strength that let her break the chains.
