She religiously watches guilty pleasure TV and regularly returns to the stable of her childhood horse.

Her track of time is melting like an ice cream cone.

Oh, and theres also something very spoiler-y about aliens, too.

Horse Girl

Katrina Marcinowski/Netflix

ALISON BRIE:We had an amazing art department and props department.

Were any of them actually personalized to you at all?

I would pick out the horse charms.

I was choosing what the color scheme was and things like that.

We had a pretty specific color scheme for the movie in general.

Peach plays such a big role in the film.

And, you know, her life is a bit sort of frozen in time.

Whats really fascinating is that nowhere in the story do I feel like it turns into a comedy.

It could have come out that way.

What happened in the scriptwriting process to see to it it hit the right tone?

I think I framed it as a sci-fi thriller.

You know, a sweet girl working at a craft store.

Its me and Molly Shannon.

That was kind of intentional.

What I really like about this story too, is how other characters kind of bounce off of her.

And specifically, Sarahs friendship with Nikki, her roommate.

I think it was really fascinating to see how that kind of plays out throughout the movie.

What was the inspiration behind her character as you guys were writing it?

Originally, the roommate, she was a much angrier character.

She was almost like the villain.

She was originally scripted to kind of be much closer in age to Sarah.

That was something that I felt like a lack of awareness as a person of a different generation.

Speaking of the generational gap.

Your characters relationship with Molly Shannons character at the craft store is a little different.

She really tries to take care of you while youre kind of going through this moment.

Yeah, we crafted Mollys character to be a very maternal character.

You and Molly Shannon were also both inPromising Young Woman.

What was that realization like when you saw that she was also in that movie?

We were never on set at the same time.

First of all, we wrote this role for Molly inHorse Girl.We just called the character Molly.

We finally changed it because we thought she maybe wouldnt feel comfortable.

A funny point to that too is my character inPromising Young Womansname was originally Alison.

They changed it to Madison at the last second.

They were like Hmm, I dont know if she wants to be totally associated with her actions.

Shes been in all of Jeff Baenas movies.

We worked together onThe Little Hours.

Shes so fun to work with.

We always had her in mind for this role.

How did you know you wanted to take it that far?

It was really part of the original idea.

I always envisioned how the movie would end.

I think weve seen so many movies where the twist is that the persons crazy.

You think of likeFight CluborMr.

Robotwhere youre like What, they have multiple personality disorder!?

This woman doesnt have the tools to know if whats happening is real or not.

She doesnt have the ability to trust her own mind.

Isnt that much scarier?

What if it really was happening?
