In 1994, Kate Winslet made her feature film debut in Peter Jackson’s “Heavenly Creatures.”

Winslet is also the proud mother of three kids.

When Threapleton arrived on October 12, 2000, Winslet embraced the role of mom.

And now, Threapleton’s all grown up and crying on-screen, too.

The project is an adaptation of an unfinished Edith Wharton work of the same name.

Notable co-stars on the project include Alisha Boe and Christina Hendricks.

Threapleton’s role in this historical drama promises to be a significant step forward in her burgeoning acting career.

This project was part of the “I Am…” female-led anthology series produced by Channel 4.

Opposite her, Threapleton played the character of Freya, Ruth’s teenage daughter.

However, Threapleton didn’t let any of it get in the way of her performance.

Critics and audiences alike were wowed by Threapleton; theIndependentcalled her a “revelation.”

It should come as no surprise, but Winslet sure seems to be her kid’s biggest fan.

And for how Threapleton felt about working alongside her veteran actor mom?

By all accounts, she cherished the experience.

As Threapleton told British Vogue, “I feel like it brought us closer.”

They not only co-starred in the episode, but Winslet co-wrote it.

The mother-daughter duo attended in perfectly coordinated black ensembles.

Both wore their hair in effortlessly tousled messy buns and donned statement earrings.

The highlight of the evening came whenWinslet was awarded a BAFTAfor her portrayal of the show’s titular character.

As she stepped onto the stage to accept her award, her emotions were palpable.

We did this together, kiddo.

Threapleton was moved to tears by her mom’s speech.

“I wanted to hug her and make it stop,” Winslet confessed.

On top of resisting their real-life instincts, Winslet and Threapleton also had to improvise their dialogue.

Perhaps unsurprisingly, Winslet and Threapleton fell right into the improvisational process and naturally played off of one another.

Her mom, Kate Winslet, wasn’t exactly shocked by this pivot.

“I think I knew [it] was coming, actually.

I think I always suspected,” Winslet said on “Lorraine” in 2021.

The opportunity couldn’t have come at a better time for Threapleton.

Clearly, the plan worked out.

And of course, that was my biggest fear and most important for her self-esteem, of course."

Winslet would reinforce affirmations like, “We are so lucky that we’ve got a shape.

We’re so lucky we’re curvy.

We’re so lucky that we’ve got good bums.”

“My daughter’s generation have an ability to speak for themselves,” she toldThe Timesin 2022.

“When I was younger you spoke when spoken to.

That is not the case now.

Young women are stronger.

And they’re prouder of their bodies.”

“[Visiting a set] was always a special treat,” Threapleton shared withVariety.

“I loved every second of it.”

(Winslet also happened to meet Mia’s dad, Jim Threapleton, on that set.)

A few decades later, Carin worked with Mia Threapleton on Apple TV+’s “The Buccaneers. "

In a 2023 interview withHello!, Carin sang Winslet’s kid’s praises.

“She’s definitely one to watch,” Carin said.

I feel as though she’s got the whole world ahead of her.”

The veteran costume designer also said she assumes Winslet must be the ideal role model for the up-and-coming actor.

Spoiler alert: It isn’t “Titanic.”

The veteran actor went on to say that her kids love the soundtrack, too.

So, Threapleton’s love of “Eternal Sunshine of the Spotless Mind” is all the more special.

“I’ll hear from someone’s bedroom, Beck blasting.

I’ll be like, ‘That’s “Eternal Sunshine."’

So that’s kind of amazing,” she said.

As noted inHeatmagazine, Winslet’s former co-star and longtime pal is “Uncle Leo” to her kids.
