It was crazy because it was last minute and I had to change my entire schedule around.
They were so incredible with me.
They all said, Got it.
Go do it, girl, and just fly to us after that.
They were really extraordinary in making this all work.
My agents said, You HAVE to make this work!
I had all these people supporting me to have this come to fruition and Im so excited.
It was a most special experience.
Were you aware of the Miglins and this part of the story?No!
I knew the story about Gianni Versace because Ive been an advocate for the LGBTQ community for so long.
I knew the Gianni Versace part of the story and I knew about Andrew Cunanan.
So you read Maureen OrthsVulgar Favors.What other research did you do?Yeah.
You look at that script and its the map and its the landscape.
I didnt need to be searching for anything else.
It was all given to me.
Did you ever consider reaching out to Marilyn Miglin?
Or did they discourage you?No.
First of all, nobody said anything to me.
I dont think it works to reach out.
They gave me all the help and all the information I needed.
I work on a character from an artistic perspective and from a psychological perspective and thats how I work.
I dont need to know everything that goes on.
Also, this is a very sensitive subject.
I think its right to be careful in the way you relate to people and deferential.
What do you think of this marriage?
Was it a marriage of friendship?I literally have no idea.
You know how you look at some people and you go, What are you doing together?
You would never do that with Lee and Marilyn.
You dont know what draws people together.
We have no idea.
That I think is such an important topic when were relating to this relationship.
So you have to honor him and have to honor her for seeing what they had.
The other stuff is private and intimate and who knows?
We have no idea.
How was it working with Mike Farrell?I loved him.
You talk about somebody who was an artist and he was so kind and so gentle.
He loves to do the work and we were connecting on all these different levels.
I had such honor for him and such respect for him for so long.
I think hes remarkable.
I just adored working with him.
We would just have these little things.
Theres one part of the episode where Im honoring him, speaking about him.
It was very special with him.
And we practiced ballroom dancing together and that was great!
That final moment where you remove your make-up and finally crack is so emotional.
It was just this kind of generous dance of everyone doing their work to support everyone elses work.
Thats all I can tell you.
It took a long time to do it and we did it over and over and over again.
The LGBTQ community is a most extraordinary, powerful, dynamic community that has been shoved aside.
This didnt have to happen.
