Kate Winslet recently shocked fans when she alerted them to her daughter Mia Threapleton’s little-known acting career.

Threapleton, whose middle name is Honey, is the Oscar-winner’s 20-year-old daughter. Her name is taken from filmmaker Jim Threapleton, Mia’s father and Winslet’s first husband. The pair were married in 1998 and divorced in 2001.

She is Winslet’s eldest daughter and has several siblings.

Her step-siblings include Winslet’s 17-year-old son Joe – whom the actor had with ex-husband Sam Mendes – and seven-year-old Bear Blaze, whom Winslet had with her current husband Edward Abel Smith.

Threapleton – who is not on social media – is signed with United Agents and has two film credits to her name, including the lead role in the 2020 independent film Shadows.

In it, she stars as Alma, a teenage survivor of a catastrophic event. Together with her sister Alex, they reside deep in the woods with their mother who shelters them from an ominous presence called the Shadows, which live in the daylight.

Speaking about her breakout role, Threapleton told Variety that she read the script and “didn’t put it down, which is admitting a lot because I’m dyslexic and that means I have to read slowly and steadily to be able to absorb things fully sometimes”.

Threapleton also made a minor appearance in Winslet’s 2014 film A Little Chaos, starring alongside her mum as well as Alan Rickman and the late Helen McCrory.


Despite Winslet’s celebrity status, Threapleton said that as a child she “never actually spent much time around sets that my mum was working on.”

“It was always a special treat,” she said.

The publication reports that Threapleton finished school and her exams between roles, and now has more time to audition on a regular basis.

Speaking on Lorraine earlier this week, Winslet confirmed her daughter’s involvement in a new TV series, which she is currently shooting in the Czech Republic.

A title for the forthcoming show is yet to be announced.
