Natalie Portman has pretty much been amazing in every movie she’s taken on — from 1995’s Beautiful Girls to the Thor films. But, that doesn’t mean that such a seasoned actress doesn’t get nervous every once in awhile on set. And, according to Portman, that was exactly the feeling she was experiencing when stepping into Jackie Kennedy’s famous shoes in her new film Jackie — pure nerves.

Entertainment Tonight got to chat up the young actress about the movie, and she was able to reveal her true thoughts about filming.

We can’t say we blame her — after all, Jackie Kennedy is pretty much an icon. But at the same time, we know that Portman got the role since she’s a pro.

One of the most notable things about Jackie? Her clothes, of course. And Portman made sure to note that wardrobe definitely helped her transform.

Jackie comes out in theaters on December 2nd — we can’t wait!
