 "Lenina Huxley" is a reference to the character "Lenina Crowne", a  character in "Brave New World" by Aldous Huxley (qv). At one point  she says to John Spartan, "You are a savage creature, John Spartan"  thus alluding to the Brave New World character John the Savage.  Also, when Phoenix picks up the ray gun after it has finally  charged, he says "Its a brave new world."
