The actresses star as BFFs on the decade-spanning Netflix drama series.

Nothing fuels the feels like BFFFFs (best fictional female friends forever)!

We may need a second season to confirm.

It was pretty instant for me.

It felt really familiar to me and I’m a big reader.

But I was just so re-inspired and moved by the story of these women.

FIREFLY LANE

NETFLIX

Katie had gotten the part and was working on this new show shooting in Vancouver, this Netflix series.

Dule called me, he’s like, “Vancouver’s your hometown.

You guys should chat.”

I just fell in love with it.

I fell in love with the story of these two women and their incredible friendship over these 30 years.

That’s a job I’m really glad I don’t have.

So was Maggie a big part of the reason for signing on?

Did she just feel like the right person to bring this story to the screen?

I actually had met Maggie through a friend, actually through my real-life Tully like, 20 years ago.

So I already knew her and loved her and didn’t know her well.

The way that she writes for women is unbelievable.

Reading the scripts was very much like sitting there bingeing on Netflix.

You just wanted to binge the scripts.

I’d finish one, and I’d be like, “Wait, I want more.

What happens next?”

It’s obviously super rare and such a gift as an actor to get material like that.

Were there any scenes that you were particularly excited to get to when you were reading the script?

Or anything you weren’t looking forward to so much?

Oh my God, I can’t wait to try that.

I can’t wait to play that.

That seems so scary and I can’t wait to do it."

The only one that I was actually so terrified about that I wasn’t excited was karaoke.

As Katie well knows, I was not born with the gift of song.

My sister and I both were kicked out of choir in grade five.

So Maggie’s like, “You’re going to do karaoke.

It’s going to be Eminem and you’re going to rap it.”

I was like, “So fun.

Definitely as a young adolescent teenager.

Awkward, uncomfortable in my own skin, super insecure and self-conscious.

I’m much better at 40 than I was at 20, though, I’ll give you that.

I’m getting stronger and just tired of it.

Tired of my own self-doubt and neuroses.

CHALKE:One hundred percent Kate in so many ways.

I definitely [see myself] in that piece and the awkwardness and fumfering over her words constantly.

Now, the motherhood piece of it, I can relate to so much.

How’s motherhood going to change me?”

On the show, Kate’s daughter Marah does not give her an easy road.

For me though, it was when we did the aerobics.

I read that in the script and I was terrified and then we had so much fun.

We put them on and we were dancing.

HEIGL:I agree.

I feel like that leotard thing just made me feel sassy.

I just felt so Tully sassy in that ensemble.

The 2000’s bootcut jean was the worst look on me ever.

I would burn every pair of bootlegged jeans ever in the world.

Firefly Laneis available to stream on Netflix beginning Wednesday.
