In an apparent leaked detail of the Star Wars: Underworld tv show (yes, it's getting a live action tv show now too), a thing has been suggested that could probably annoy the fans of the original movies.

Namely that: Seemingly taking a page from the recent Star Trek movie, the show will involve a bunch of Rebels using time travel to go back to try and stop Darth Vader from ever existing. Whether this means trying to murder Anakin as a child or just stop him from turning to the Dark Side, I don't know. Could potentially erase the original movies and form an alternate timeline like the JJ Abrams movies... but I personally think that it's more likely that it's going to revolve around the Rebels trying and failing to change the future, or through their actions causing Vader to be created purely by their attempts to stop it from occuring. Or something.
Personally I think that this could be interesting, as although I've seen the original films I'm not exactly invested in the franchise to the extent I am in, say, Doctor Who. Or even frigging Captain Scarlet.
