Leo discussed how different it was revisiting Daisy and Gatsby's relationship as an adult after studying the novel in class back when he was in high school. He said, "The Gatsby that I remembered reading when I was 15 years old in high school was far different from the Gatsby that I read as an adult. From what I remember in my years in high school was that I thought he was a hopeless romantic who was solely in love with this one woman and created this great amount of wealth to essentially pull her in. But then to reread it as an adult, I found it incredibly fascinating. It's incredibly nuanced, it's existential, and here, at the center of this movie, is this man that is incredibly hollow — he's searching for some sort of meaning in his life. He's attached himself to this relic known as Daisy — she's a mirage. I was struck by the sadness in him for the first time. I looked at him completely differently. I looked at him as somebody that was very hollow and searching for some sort of meaning. That was the Gatsby that I was incredibly excited about as an actor."
