"You know what would be a cool Easter egg for the fans? The new Death Star that's 100 times as large...? We'll call it Starkiller base. Cause you know Skywalker's original name was Starkiller."
It's astounding how you people will start whining the second that sequels are mentioned. Even if it's tangentially related, or Star Wars is, or if it's not the focus of the joke, it doesn't matter. Just insta-complain.
Maybe... but Skywalker was definitely originally called Starkiller back in the 70s before Lucas changed it to a more positive sounding name. It was in one of the original scripts.
EDIT, from Wiki:
George Lucas considered various characterizations for the protagonist of the original Star Wars film.[s] The possibilities included a 60-year-old grizzled war hero, a Jedi Master, a dwarf, and a woman.[5][6] Luke's original surname was "Starkiller", and it remained in the script until a few months into filming. It was dropped due to what Lucas called "unpleasant connotations" with Charles Manson, who became a "star killer" in 1969 when he murdered the well-known actress Sharon Tate.[7][8] Lucas replaced the problematic name "Starkiller" with "Skywalker".[9]
