"You don't become the character"

When Peter Fonda states "you don't become the character," he may be referring to the truth that as a star, you are merely playing a role. While it might be tempting to completely immerse oneself in the character and adopt their traits and mannerisms, ultimately, the actor should stay knowledgeable about their own identity and not lose themselves in the role. The declaration might also suggest that the actor's task is to bring the character to life and give them depth, but at the end of the day, the character remains a different entity from the actor. It is essential for stars to strike a balance in between embodying the character and maintaining their own distinct existence.
