The just released BioShock Infinite "Tears" video details Elizabeth's power to open tears in the fabric of space-time. Check out the freeze-frame above; it shows off the destination of a tear, which is clearly an alternate 1983.
See the marquee? "Revenge of the Jedi" was the original name of Return of the Jedi, changed by George Lucas because Jedi don't seek revenge. Somehow, in Bioshock Infinite's alternative future, the name of the movie never got changed, or Jedi are more vengeful. Or maybe they didn't want to pay for the rights? Either way, Bioshock Infinite is blowing my mind right now.
