Collider: I read that you almost didnt take this role because it seemed so intense.
Did you have to convince yourself to do it?
Did someone talk you into it?
What eventually got you to sign on?
But it was mid-Bad Sisterswhen it came in and I was like, How is that gonna work?
And they were like, Oh, theyll wait for you.

Youll have a couple of months off.
The end of Season 1 ofBad Sisterswas pretty tough going as well.
She was like, Just talk to the director.
And Michael Keillor was just so lovely and easygoing.
He was like, Dont worry about it.
Well just film it, say Cut!
and you wont have to do it again.
Im not gonna keep the camera on you.
I also had that thing whereI didnt love the idea of someone else playing the part.

I really connected to her.
And so, I just thought, Fuck it.
But when I was doing it, I was destroyed.
It was very hard to not take it home.
Its such a brutal story and there were so many scenes that just take you apart.
You just had to be really nice yourself and find those moments to have a laugh.
Michael Sheen and I laughed.
When we werent crying, we laughed all the time.
Everyone involved in it was quite mindful of the fact that we had to also look after each other.
‘Best Interests’ premieres February 17 on Acorn TV.
What did you do to shake it off when it was over?
How did you check that that you were being as authentic as you could be with this?
HORGAN: Thats a really good question.
Our rehearsal period was all just talking.
We werent trying out scenes.
We were all just talking and bringing that authenticity to it.
The most interesting relationship in this, for me, is the one between Nicci and Katie.
What was that like to dive into?
How did you find that dynamic and ensure it was also important to the story?
She could have easily been pushed to the side and forgotten.
HORGAN: I totally agree with you.
It was the only thing that we initially maybe fiddled a bit with very early on with Jack.
They are the love of each others lives, and I can see that with my girls.
So, I found those scenes very, very authentic, but they broke my heart.
We adjusted that early on, so it wasnt quite so cold.
Nicci is not a cold mum, she just is fucking laser-focused on what she has to do.
Im such a fan of Alison Oliver.
Shes an incredible actor.
Its never gonna be a forgotten bit of the story with someone like her playing that character.
After doing this, did you want to do something that was straight comedy?
HORGAN: You always have exactly that.
When you do a really stupid comedy, you go, I need to do some drama.
And then, you have exactly the same thing when you do something dark.
You just wanna do something that that has some levity in it.
Is there any chance well get a Season 3 ofBad Sisters?
Are you missing them enough that youve come up with some ideas?
HORGAN: I will always miss them, and thats the truth.
I love those girls and I loved playing their sister.
Theyre always in the back of my head.
The Season 2 finale ties up many loose ends.
What does the existence of that show mean to you?
It still feels like, Fuck, did that happen?!
We got to be as authentic as we wanted to be.
We didnt have to pull back on any of the Irish-isms because it turned out that people loved it.
I feel really, really lucky and grateful.
I think about it a lot.
Would you ever want to do aGame Nightsequel?
Theres been talk of one a few times over the years.
Have you ever had any serious conversations about it?
Is that something youd want to do?
They were such a great bunch and I loved it.
I absolutely loved that experience so much, so if it happens, Id do it.
But I think I would have heard something if there was any chance.
You probably know better than anyone how hard it is to duplicate something.
How do you duplicate or live up to those expectations, with another season or a sequel?
It would have been fine.
You berate yourself a lot along the way and you go, Why did I do this?
But then, when it works out, it works out.
Do you know what youre going to be doing next?
Im doing a new Hulu show (playing Amanda Knoxs mother inAmanda: A Coming of Age Horror).
Im in Budapest at the moment, filming that.
There are a couple of really exciting things.
HORGAN: Completely different.
This thing, at the moment, couldnt be any more different.
It would never have come out of my own mind.
And then, it all becomes a bit like youre just plodding along.
I just want to do something Ive never done before.
The hardest question is when youre asked, What do you want to do next?
Theres never a grand plan.
I want to do something that frightens me and surprises me.
Then, it just keeps you on your toes.
