She is fantastic - but I do question her character as she is good friends with the abominable Mel Gibson. How anyone can support that douche is beyond me
Apparently he stuck by her when she was blacklisted by Hollywood film industry (after a crazed fan shot Reagan for her.)
He helped her get acting work again, and he also helped her get her first directing role.
That's what I read anyway, and it seems believable considering how she's sticking by him now.
