Moore said moving around a lot as a child helped her study behavior and become a better performer.
Growing up, Julianne Moore's family never stayed in one place for very long, and while there were challenges for her, she said her globetrotting childhood helped her become a better actor.
"For me, I think what I saw was that people believed that identity was solid and somehow about where you were from. It's like, 'You are this,'" Moore told Willie Geist on Sunday TODAY."We define ourselves by the town we're from, where we grow up, where we go to school, who we are friends with and it feels like that's somehow you and it's not, because its changeable, its mutable.
Moore has earned raves throughout her career for her wide range, tackling comedy in the cult classic"The Big Lebowski" to drama in"Still Alice," which earned her an Academy Award in 2015. Her latest project, the limited series"Lisey's Story," is an adaptation of the Stephen King thriller and can be streamed on Apple TV.
