“It was important to find the emotional truth in this character. One of the biggest themes in this movie is the private and public self. Norma Jeane was completely unseen. I wanted to capture the essence of that woman, to find the human underneath. It was a long process studying her and her films, to understand what she was feeling at all times, always thinking that Norma for the most part never thought she could live up to Marilyn. What people thought of her was not at all what she felt like.”

He also spoke about how impressed he was with watching de Armas perform, feeling that the actress perfectly captured what it was that she was trying to convey with portraying Norma Jeane.

“Her beautiful portrayal [depicts the] fragility and loneliness and the how far away that is from all of our perception and what Hollywood perpetuates about stardom, success. … It was very important to try to convey some of complexities in that relationship. The love that has to be there, the potential for hopefulness that is messing in so much of her life and that she is longing for.”
