Mia Threapleton has opened up on sharing the screen with her mother Kate Winslet, and revealed the key piece of advice she has given her.

The actress, 24, has followed in her famous mum’s footsteps, starring in the likes of The Buccaneers and Firebrand, before landing her biggest role yet, as a lead in Wes Anderson’s latest film, The Phoenician Scheme.

While she won critical praise in 2022’s hard-hitting I Am Ruth, where she starred opposite Kate, 49, playing a mother and daughter.

The Channel 4 drama saw Mia play a troubled teenager battling a mental health crisis after becoming consumed by the pressures of social media, while Kate took on the role of her concerned mum Ruth, trying to help her daughter through her struggles.

And while it won rave reviews as well as BAFTAs for Best Single Drama and the Best Actress gong for Kate, Mia has admitted that it was challenging working with the Oscar winner. 

The pair shared many heavy and emotionally-fraught scenes onscreen, with the dialogue in their shouting matches being improvised.

In a new interview with The Sunday Times, Mia admitted that sharing that tension with her real life mum was no easy feat, with Kate making it clear that they would leave their characters’ feelings on the set.

She said: ‘It was quite frightening at times, because both of us were going into extremely emotionally intense places. I remember [Kate] saying to me when we started, “We can’t be sad all the time. We have to be able to come home and have a lovely cup of tea and a biscuit”.’

However, having one of the greatest British actors as a parent also means a wealth of advice at your fingertips, with Mia revealing Kate has gifted her some solid acting tips, chiefly: ‘Read the damn script as many times as you can!’

She explained how she had first told her mother she wanted to follow into her footsteps and be an actress herself at just 10 years old, and described Kate as being ‘quite caught off-guard’ by her aspiration. 

She explained how she has signed herself up to online casting sites at the age of 15, out of her desire to do it ‘on my own’.

While she added that Kate has been nothing but supportive of her career in the industry, while also making sure that she was aware of the difficulties that came with the job.

Mia said: ‘She was very, very encouraging of me doing it on my own and for myself, having the experiences being mine and mine alone. But she always – I mean, always – emphasised the hard work that goes into it and the effort that needs to go into it.’

Kate previously gushed over her experience working with her daughter, saying she was ‘blown away’ by her courage on set.

The film industry veteran insisted Mia didn’t need her advice and would even tell her to ‘shut up’ and proudly gushed that her daughter has a ‘power’ that she herself never had as a young actress.

Appearing on Lorraine in December 2022, she explained: ‘As far as performance, she didn’t need me at all. There are even moments where she’d look at me and go, “Shut up Mum, let me do it!”

‘It was really amazing working alongside her and actually being blown away by her courage… she’s very, very powerful.’

And in her BAFTA acceptance speech for the role in 2023, the тιтanic star gave a sweet tribute to Mia, saying: ‘If I could break [the award] in half, I would give the other half to my daughter Mia Threapleton. We did this together, kiddo!’

Mia, who Kate shares with film director Jim Threapleton, has previously hit back at claims she is a ‘nepo baby’ or that she had a helping hand in the industry through her mum.

Earlier this week, she claimed her famous parentage has led to a ‘misconception’ that she was submerged in the acting world from an early age.

She said: ‘I feel like it’s a misconception about me, considering who my mother is, that I grew up going to set or that I would know anything about this world because of her and what she does.

‘That is not the case at all. I genuinely can count on not even two hands the amount of times I went to set as a kid. There were never scripts lying around the house.’

And in her BAFTA speech, she gave Mia a sweet tribute, saying: ‘If I could break [the award] in half, I would give the other half to my daughter Mia Threapleton. We did this together, kiddo!’

And she has previously insisted she didn’t get to spend much time learning acting skills by watching Kate work as a child. 

Speaking to Variety, she admitted: ‘I never actually spent much time around sets that my mum was working on. It was always a special treat.

‘It’s a very different experience when it is happening to you, and not just something I was getting to observe from time to time. 

‘I really understand why my mum has always impressed on us how hard the work is. She is right! And I loved every second of it.’ 

Earlier this year, Mia scooped the Breakout Artist Award during the Newport Beach Film Festival UK & IE Honours 2025 in London at the same age that Kate was when received her first Best Actress Oscar nod for тιтanic.

Mia made her own acting debut in 2014’s A Little Chaos, in which her mother starred, followed by a role in 2020 thriller drama, Shadows.

She then made waves with her performance in I Am Ruth, and is currently starring in the Apple TV+ adaptation of the Edith Wharton novel The Buccaneers.

Kate has also been insistent that Mia is not a ‘nepo baby’ and that her success is down to her own talent.

She previously said: ‘What’s great for her is she has a different surname so she slipped under the radar and the people who cast her didn’t know she was my daughter and that was important for her self-esteem, of course’. 

Kate met Mia’s father Jim on the set of Hideous Kinky in 1998 where he was ᴀssistant director and they tied the knot the same year.

The couple went on to welcome Mia in 2000, but then divorced just a year later.
