Beware Greeks Bearing Gifts - S1-E12
Revealing mistake: At the end when Xena is fighting Deiphobus, he pushes her up against a large rock, every time she hits the rock it moves, as if it were foam.
Revealing mistake: When Alesia is hanging off the cliff, the long shots are obvious doubles. Alesia is a 7 year old girl, and the double is an adult, the legs are much much longer. (00:27:30)
Revealing mistake: When Gabrielle is hitting her staff against the tree and screaming, if you look carefully for the last hit, the staff is bent. Most of their props were rubber with a metal rod inside them. The actress bent the metal rod because she was hitting so hard.
Revealing mistake: When Xena is explaining to Gabrielle what happened at Cirra, her native New Zealand accent can be plainly heard when Xena says "ordinary".
Revealing mistake: After Xena gets out of that chair, she does a swinging kick from her whip and you get a shot of her feet connecting with her victim's chest. The fake feet that are used are seen bending backwards.
Beware Greeks Bearing Gifts - S1-E12
Revealing mistake: In the beginning battle, as the Trojans fight from the top of the gates of the city, one falls off. The entire Stone Wall shakes when he hits it.
Revealing mistake: When Xena and Gabrielle are in the hot tub, there is a part where Gabrielle turns to face Xena, and when she does the actress stood up to far. You can see her bathing suit when she is supposed to be naked.
Adventures in the Sin Trade (2) - S4-E2
Revealing mistake: When Xena and the other Amazons see the remains of the Amazons Xena killed, look carefully in the wide shot. The skeleton in the foreground {lower right side of the screen) has his middle finger up.
Revealing mistake: When Callisto holds the chakram with one finger, you can see the stick she's holding that makes it look balanced on her finger. (00:16:20)
Revealing mistake: When Xena drags Gabrielle with the whip behind her horse, you can see in some shots it is a dummy - as the arms are in a static position. In other shots, Gabrielle is a man, as shown by how much larger she suddenly gets. (00:02:00)
The Haunting of Amphipolis - S6-E2
Revealing mistake: When Xena comes in and checks on Gabrielle, a possessed Gabrielle is hanging from the ceiling naked. In the long shot you can see her nude suit and the wires holding her up.
Revealing mistake: Just as Cupid's son flies up to get an arrow, you can see the wire holding him up to make him fly. Only visible in the quick shot of the child over the bed. (00:01:50)
Revealing mistake: When one of the Horde Warriors kills one of Xena's men, he slits his throat. You see the slit throat and blood before the Warrior makes the cut. (00:00:20)

A Good Day - S4-E5
Revealing mistake: Xena cuts the throat of a Roman Warrior during battle, there is a red line on his neck prior to the cut, and the knife makes no mark on his neck. (00:31:45)
Revealing mistake: There is an Amazon ritual being performed where the character has to be cut on the arm, but you can see the blood on the knife before the blade touches her arm.
Revealing mistake: When Hope and Gabrielle are talking, and Gabby says she's sorry the poison didn't kill Hope, look when the camera is on Hope and behind Gabby. Since Renee O'Conner plays both parts, a double is used from the back. The double is really bad. Her build is way too small and un-muscular to be Gabby.
Revealing mistake: Xena rides by on her horse, Argo. It is her stunt double, and not Lucy Lawless. (00:10:20)
