"I think it's damaging to know too much about a person, about an actor"

Molly Parker's quote suggests that knowing excessive about a person, especially a star, can be damaging. She implies that it can be challenging to separate the person from the character they depict, and that this can be a barrier to the actor's performance. It can be tough for an audience to suspend shock if they understand too much about the actor's individual life, as it can be sidetracking. Additionally, if a star is too well known, it can be tough for them to take on different roles, as the audience may have trouble seeing them in a various light. Parker's quote suggests that it is best to keep some secret around an actor, so that they can be seen as a character rather than a person.
