1. Her starring role for impressive budget Brit flick Jellyfish required her to do a Frankie Boyle-inspired stand-up routine.
‘It was very stressful because it was a live audience. They didn’t have enough money to pay for extras so all these random Margate people turned up. And the lines weren’t even in my head because they changed the script the morning we shot it. And I got a heckler. I probably would have cried on stage if it had been me in real life’.
2. She was embarrassed about becoming an actor.
‘When I started secondary school I thought that drama was for absolute… let’s say “geeks”. And so I shunned it — ignorantly. Then, when I was 14, I suddenly found a monologue from Roald Dahl’s The Witches and that ignited a fire I’d forgotten about. I absolutely loved Anjelica Huston in the film adaptation but I didn’t tell anyone for years that I wanted to be an actress. I just practised secretly in my bedroom.’
3. Her career icon was Leonardo DiCaprio.
‘He did This Boy’s Life when he was 16, and What’s Eating Gilbert Grape and all these youngish roles, and it really gave me inspiration to want to get a job by the time I was 16. And I got Three Girls [a 2017 BBC miniseries about the Rochdale sex abuse scandal] and it was amazing. Since then I try not to compare, just to admire.’
4. Before her Bifa most promising newcomer nomination for Jellyfish, she was Bafta-nominated for Three Girls.
‘I feel very fortunate and it’s all downhill from now!’
5, She’s about to move out of home in Derbyshire to London to play in Top Girls at The National Theatre.
‘It’s really exciting. I’m sharing digs I found on theatredigsbooker.com with a lovely lady and her nice black cat. I’m looking forward to experiencing adult life without my mum but I know I’m going to be homesick. On my last day at home, my mum’s going to make a lasagne and I’m going to bake fairy cakes.’
