The majority of Gabrielle's stunts and fight scenes was performed by Renee O'Connor herself, including the backflip from "The Abyss" where Gabrielle kicks a cannibal in the face mid-flight, which was done without any wirework.
Much debate surrounded the possible lesbian relationship between Xena and Gabrielle, which the writers deliberately kept ambiguous. Since the demise of the show however, Lucy Lawless has stated that she believes the characters were romantically involved.
Gabrielle had a total of 7 regular outfits over the course of the series. Starting off with a Greek Farmgirl's dress in Season 1, Gabrielle would upgrade to 3 different Amazon outfits, a yellow two-piece Indian garment and two warrior bikini costumes.
In 1996 while rehearsing a skit for The Tonight Show with Jay Leno (1992). Lucy Lawless fractured her pelvis when she was thrown clear from her horse. As a result, several episodes of Season 2 had to be edited to accommodate her recovery: some of them were changed so Lucy could have a very slight appearance (in one episode she only appear as archive footage), and they created some brand new episodes.
Robert G. Tapert on why and how he picked Xena's weapon: "I had a book of ancient weapons and I saw this weird discus called the Chakram and I said let's give her this because it can return and we'll never have another character use it. John Schulian [series writer] said he hated it and said we should cut around it. I told him 'that weapon is the coolest thing I'd ever seen' - it's her signature piece".
Gabrielle's fighting style was a mix of martial arts, kickboxing and acrobatics. Her two trademark weapons - the fighting staff and the sais - are both part of a Japanese fighting style known as Okinawan Kobudo.
Before her own series, Xena made her debut in a three-episode arc of Hercules: The Legendary Journeys (1995). Vanessa Angel was the original choice to play her, but when the actress became too ill to fly to New Zealand to film, Lucy Lawless was cast instead.
Karl Urban was originally intended to reprise his role as Cupid during the "Twilight of the Gods" storyarc in Season 5, but was unable to return due to filming "The Lord of the Rings" trilogy as the character Eomer. Karl Urban eventually returned in Season 6 as his equally popular character Julius Caesar. When asked about the fate of Cupid at a convention, Karl replied that he remained at Mount Olympus with Aphrodite and Ares - the only two surviving Greek Gods.

While she was auditioning for the role of Gabrielle, Renée O'Connor was standing on a chair reading the lines for Robert G. Tapert. Renee fell off the chair, which made Tapert remember her while he was casting.
The planet Eris which was discovered in 2005, was nicknamed Xena, after the heroine of the TV series, by the team that found it. Though it wasn't given the name officially, it's moon was named Dysnomia, after the Greek goddess of lawlessness which bares a similarity to the name of the actress that plays Xena, Lucy Lawless.
The show was originally set in Greece, but by the third season the show began to take place in Rome, Egypt, China, Japan, Siberia, Norway, North Africa and India. In addition to the Greek mythology, Hinduism and Christianity were also introduced through several story arcs.
In the end titles of almost every episode there are a few funny lines, known as "disclaimer", which usually end with "the production of this motion picture". They're related to the content of the episode. Several episodes in Season 1 have no disclaimer; from Season 2 onwards every episode gets one.
The shows first two seasons were shot in 4:3 aspect ratio. From the third episode of the third season onwards (the first two episodes were actually shot at the end of season 2), it was filmed in 16:9 widescreen.
There are two "The Simpsons" toy action figures of Xena/Lucy Lawless based on the 1999 Lucy Lawless' appearance in the "Treehouse of Horror X" special, "Desperately Xeeking Xena." The second one was released in 2014 as part of the 25 greatest guest stars series.
Sam Raimi is such a huge fan of Hong Kong cinema that the series was influenced by it. One such influence was Ching Siu-Tung's A Chinese Ghost Story (as can be seen in The Debt, Part 1). More influences can be detected if you browse the Xena + Hong Kong Connection site.
In a 2011 memoir at Alex Belth's Bronx Banter blog by one of Xena's creators, John Schulian, titled "From Ali to Xena" chapters 43, 44, 45 he describes how the character of Xena was created, and the success of casting Lucy Lawless.
