They also reveal the one request their legendary guest star had before signing on for the thriller-satire show.

Talk about growing pains.

“Bingo,” Anna says, as the credits roll.

RACHEL RAMRAS:[Laughs] I think the problem was with Buell.

I think that mailbox was very easily fixed.

And what about the recurring casserole dish?

Where did that come from?

And diving into the finale, did you always have Emma pegged as the murderer?

HUGH DAVIDSON:When we were first writing, we knew we had to have a shocking ending.

But I think we spent weeks before we got to Emma, the kid.

We were just trying to figure out the characters, and who would be the most shocking person?

And turns out it’s an 8-year-old girl.

Then it turns out you might.

So it’s possible for you to make it the most obvious or the least obvious person.

But it was more fun to have it be Samsara [who plays Emma].

Really everything was kind of on the table since this was gonna end comedically.

So it just had the most legs for an ending, comedically.

She had so much fun, I have to say.

She was looking forward to filming that from day one.

Samsara’s little baby teeth were growing in.

[We had] a great stunt coordinator and the choreography was great.

They had a lot of fun.

They were both committed.

We had to write a different monologue just for casting.

And that was shocking to see these young girls say the worst, most terrible things.

RAMRAS:More shocking that the parents let them.

DAVIDSON:And then the most shocking that Samsara was so great at it.

[Laughs]

What were the logistics of the actual fight itself?

RAMRAS:We did have stunt doubles, but our editors were so fantastic.

I think they did a really seamless job where you could’t really tell.

It just took a lot of creativity.

And we didn’t want to use a lot of props.

But most of the fight is Anna trying to defend herself.

The other big moment from the finale, of course, is the cameo with Glenn Close.

How did that all come about?

I was just talking and talking and she was listening.

And I kept thinking, “Oh, God, what is she thinking?”

DAVIDSON:And Rachel said, “Okay!”

[Laughs]

RAMRAS:She obviously has a great sense of humor.

She was such a team player, and she seemed to have a lot of fun that day.

It was a really quick couple of hours of shooting.

I bet she’s a fun one to work with.

DAVIDSON:It’s funny.

Rachel read all the books and then Rachel made me and Larry read the books.

RAMRAS:It could.

We’ll see if people like this first one.
