I want to double-check that we’re telling it how she would’ve wanted.
You get to work quite closely with Colin Hanks andAnna Paquin, as they play your parents.

I don’t know many other people like that.
Colin Hanks I told him that I was going to say this the last day when I wrapped.
You are so cool."
Both shows are about women who were coerced and had to find their own voice.
