Julia has been writing her own scripts and making her own short films for years (yes, she's 10!). During her free time while filming Once Upon a Time in Hollywood, Julia wrote and performed one of her scripts. While she was working a gust of wind blew all of her pages away, and she told The Hollywood Reporter that "Luke Perry just ran all over that set, catching the pages and collecting them. He put them in order and he stacked them up nicely." Ultimately, Julia wants to become a director, and she said she got a lot of advice from Tarantino, whom she now considers her mentor.
