i recently went to go see kill bill the whole bloody affair in theaters so, as you can probably imagine, kill bill has been on my mind a lot lately. personally, this has always been one of those film theories that i've been skeptical about because there's even more evidence against it.
1: fox force five is stated to be a team of 5 WOMEN. the deadly viper assasination squad has 4 women and 1 man.
2: it's often said that mia's character was "the deadliest woman in the world with a knife". beatrix only uses a knife during her confrontation with vernita at the beginning of volume 1. while she's shown to be quite handy with it, she mainly uses a kitana. of course, an argument could be made that a sword is merely a large knife.
3: the "blonde leader" from fox force five is often cited as elle. elle isn't the leader of the deadly viper assasination squad. bill is.
4: one member of fox force five was a french woman. many have argued that this description matches sofie, o ren's assistant and best friend. while sofie is an associate of bill, she's not really a member of the squad.
5: in fox force five, the titular team was fully together. for most of kill bill, the team is fractured and a large part of the plot of kill bill is beatrix killing her former teammates.
so yeah. i don't buy it.
