You probably won't be too shocked to learn that nepotism exists in Hollywood: If Nicolas Cage hadn't gotten some of his earliest roles from his uncle Francis Ford Coppola, the world would be a sadder, less crazy place.

Now we know why -- he was Obi-Wan's freaking uncle and had the Force on his side all along.
"New plan: You guys wait here -- I got this."
McGregor says that his uncle was a huge influence on him, saying that "If he hadn't been an actor, I'm sure I wouldn't have thought to be one." Think about that. One of the best known actors in the world finds his inspiration in a guy who didn't even get an action figure in the original Star Wars toy series (and freakin' everyone did).
