Lupita Nyong'o is playing one of the characters most shrouded in secrecy in Star Wars: The Force Awakens: Maz Kanata. When we spoke with her in LA ahead of the premiere, she talked about why this version of Star Wars is great for young girls, what it was like to bring her best friend to the set, and the advice she gives her little brother, Peter . . . even when he doesn't want it.
