Renée O'Connor was not in the opening credits for season 1. At Lucy Lawless' insistence, Renee was included in opening credits from season 2 onwards.
Rob 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".
The majority of Gabrielle's stunts and fight scenes were performed by Renée O'Connor herself, including the backflip from The Abyss (2000) where Gabrielle kicks a cannibal in the face mid-flight, which was done without any wirework.
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, its moon which was originally nicknamed Gabrielle was officially named Dysnomia, after the Greek deity, which bears a similarity to the surname of the actress that plays Xena, Lucy Lawless. The Greek meaning of Dysnomia is 'lawlessness,' thus, still a nod to Lucy Lawless and the character of Xena, by the discoverer of the planet, Dr. Michael E. Brown.
