Zoe was initially hired to be the "fall over" double only, (which is the stuntie that hits the ground and is thrown into things) for Uma Thurman in the movie Kill Bill vol 1, and she was given six weeks worth of training beforehand to fulfill that role. But when they actually started shooting the film they realized that Zoe would make a great body double for Uma, so they decided to train her in her additinal role as they went along on set. That meant she was never properly trained for her fight scenes. She found it difficult, since she had only ever fought as Xena. She had to consciously avoid fighting like Xena to fight as her new character, who used a completely different of martial arts.
