Many elements of the on-screen Julia's personality and story were inspired by real-life Julia, but some details were actually taken directly from Julia Fox's life. One example is the scene where Julia in Uncut Gems gets a tattoo with her boyfriend's name after a fight, which real-life Julia actually did. When asked by Cosmopolitan about elements of the movie that reflected her own life, Julia replied, "The tattoo thing, when I got the tattoo when Howard was mad at me. I've actually done that when my boyfriend was mad at me. I went and got his name tattooed to show him how devoted and committed I was." Apparently, it worked. "It's on my finger," she continued. I still have it actually. I did it on my ring finger."
