Revealing mistake: Xena rides by on her horse, Argo. It is her stunt double, and not Lucy Lawless. (00:10:20)
Continuity mistake: In the scene where Gabrielle and Joxer are lining up the rockets, Gabrielle takes on a whole bunch of troops and she has armlets on matching her chin outfit, but when it cuts to Renee's stunt double, she doesn't have on the armlets. And it is like that throughout the whole scene.
In Sickness and In Hell - S4-E4
Continuity mistake: Right after Xena turns Joxer's hat around, she is standing there with her arms, crossed. Angle changes, and her arms are to her side, then she crosses her arms again. Happens again several times during this scenes when the shots change, her arms cross and uncross again. (00:02:50)
Continuity mistake: Xena's sword is partially out of the scabbard in the frontal shot yet fully in the scabbard in the over the shoulder shot. (00:01:20)
Other mistake: Across the show Xena's past relationship with Ares is unclear. In "The Reckoning" (Season 1), Xena says to Ares that she used to wonder what he looked like - implying that they had never met face to face. Yet in "Succession" (Season 5), Xena asks Ares if this portal world is just to watch his new girlfriend fight and he responds, saying it is to watch his old girlfriend (Xena) fight. If they had been in a relationship, surely a: Xena and Ares would have met face to face and therefore b: Xena would know what Ares looked like.
Factual error: The error begins in this episode and continues in Season 1 Episode 12: "Beware Greeks Bearing Gifts." Near the end of The Reckoning, Xena and Ares are talking about making Xena "the architect of a new world". Xena says that she'll need an army. Ares tells her she can have anyone she wants. She mentions Achilles and Agamemnon in her list of warriors and then follows up by saying "they're long gone." In "Beware Greeks Bearing Gifts," the Trojan War is going on. This is historically inaccurate as Achilles was killed in the Trojan War and Agamemnon was the leader of the Greek forces in the Trojan War and wasn't killed until after it was over. (00:36:25 - 00:37:00)
Continuity mistake: In the episode 'The Xena Scrolls,' the chakram that is buried in Ares' tomb is the chakram from the first four seasons. However, as the chakram is neutralised in the episode 'Chakram' and is given back to the cloned Xena in the episode 'The Clones', how could the chakram be neutralised before Xena dies, be separated in the 1940s when they discover the Chakram in Ares' tomb and then be neutralised in the episode with the clones?
Other mistake: In Season 2 "Ten Little Warlords," Ares tells Xena that without a sitting God of War, peaceful people can't control their anger. Yet during the whole time in Season 6 that Ares is mortal, peaceful people can control their anger. Furthermore, in Season 6, Ares tells Xena that without the God of War the Goddess of Love becomes unbalanced. Yet in Season 2 there is no mention of this.
Continuity mistake: When Pilee is banging against the gate, the first shots show the brace on the door at an angle, then the subsequent shots show it suddenly straight. (00:23:25)
Continuity mistake: When Gabrielle sees Lilla for the first time she has her hand over Lilla's mouth and through that whole scene, between shots, Gabrielle's hand keeps changing positions.
Married with Fishsticks - S5-E15
Revealing mistake: In the scene where "Crustacea" is being hung upside down in the water by the children, you can see her wig detaching on the sides by her ears.
The Convert - S4-E18
Continuity mistake: When Gabby bends down to Najara, her sari is pinned in the back. There's a quick shot to Xena, and her sari is now flowing freely at her sides. (00:10:20)
Audio problem: Xena says to Gabrielle about Solan, "Some tracker, huh?" This sentence is said in her native Kiwi accent, not the 'American' accent of her character. (00:00:50)
Continuity mistake: As Gabby is walking and talking with Aiden, from the back, you see her arms slightly bent in front of her, probably with her hands held. From the front, her arms are straight down at her sides. (00:12:00)
Continuity mistake: Xena kicks Milo's sword out of his hand, so he bends down to pick up the knife. When he turns around, his sword is back in his scabbard. (00:37:40)
The Convert - S4-E18
Revealing mistake: When Xena is climbing up into the tree, you see a clear shot of her stunt double's face. (00:39:30)
In Sickness and In Hell - S4-E4
Continuity mistake: Xena splashes the stew in Joxer's face, his right temple is bare. When he turns around and the camera angle changes, he suddenly has a large clump of stew on his right temple. (00:10:40)
The Convert - S4-E18
Continuity mistake: Najara smears blood all over her left cheek during her fight with Xena, then a bit later, the blood smear is smaller, and more on her lower cheek, rather than all over it. (00:40:25 - 00:41:15)
Takes One To Know One - S4-E19
Continuity mistake: During the fight, Joxer is hiding behind Minya. The shot changes to a wide shot, and Joxer is running out of the room. (00:35:50)
Continuity mistake: When Xena flips into the tree, her sword disappears, then appears after she lands. (00:14:00)
