When Jung Hoyeon took on the role of Kang Sae-byeok in Netflix’s Squid Game in 2021, she had no prior acting experience. Then already an established face in the modelling industry, her performance as the reserved and stoic North Korean defector earned her critical acclaim and instantly shot her to global popularity. Now, three years later, she is ready to conquer Hollywood.
Written and directed by Alfonso Cuarón, Apple TV+’s Disclaimer centres Catherine Ravenscroft, an acclaimed journalist. But when she receives a novel in the mail, she is horrified to realise that she is a key character in the story—and that it exposes her darkest secret. Jung plays Ji-soo, Catherine’s ambitious and hardworking assistant. The first in a series of prominent projects she has lined up, Disclaimer marks Jung’s first English-speaking role—and with it, a first foray into Western media.
“Around this time, right before we get to show the audiences our work, is the time that I get most nervous, because you never know what kind of response or reaction you’d be met with,” she muses. “I’m both excited and nervous, but to be faced with this unknown is more exciting than it is nerve-wrecking.”
When Jung speaks, it is with an earnestness that reveals the sincerity and seriousness with which she views acting. “The story is very intense, so I felt some pressure when I first read the script, which made it a bit scary. But at the same time, I feel like this series captures the various aspects of being human, and this made me even more excited and happy to be part of this project,” she shares.
Below, she opens up on preparing for the role, working with Cate Blanchett, and what she would like to explore with her acting in the future.

What stood out to you about the character of Jisoo?
Her actions. Did she act that way because she’s someone peculiar, or is this how an average person would behave? Watching Jisoo make these decisions made me reflect on my past, and I tried to put myself in her shoes. I was also curious to see how audiences would react to the way Jisoo acted.
Were you able to personally relate to her on any level?
We both lived overseas. After I started modelling, I had to move to New York, and I remember being really committed to my job and feeling that strong passion. I had a lot of conviction, and wanted to do really well. That was something that I could relate to, although I don’t think I was as ambitious as Jisoo is.
What was the preparation process like?
I flew into London about a month before we started filming, because I wanted to have some experience living in London like my character, and also to give myself some time and space. I remember going to Pret A Manger every morning to have breakfast, and I just tried to live the Londoner life. I spent my time practising my lines with my dialect coach, discussing my character with director Alfonso Cuarón, and doing fittings for my outfits. I like planning out my schedule in advance, so coming to London early was very helpful.
Were there any particularly fun or memorable moments for you throughout the filming process?
This was my first time acting in English, so I wouldn’t necessarily say that I enjoyed the process, because I was just super focused on producing the best results and the best performance possible. I did enjoy the tacos that we had for lunch though.
What was it like working with Cate Blanchett?
She was so graceful and kind and warm-hearted. I was blown away by her professionalism. I was so impressed by the way she acted on set, and I learned a lot about how to behave and carry myself whenever something unexpected came up. She was so consistent and calm and composed, and I learned that having that strong and firm mentality is an important quality to have to become a great actor.
How did you feel when you got to see the completed series?
I’m a little embarrassed to say this, but it was only when we premiered in Venice that I got to see all seven episodes. Right after we began screening, I needed to go to the bathroom, but we had four episodes played back-to-back without an intermission. Halfway through, I just forgot the fact that I wanted to go to the bathroom. It’s very difficult to be this focused watching a series that you were part of, but I was so immersed.
People are excited to see more of your acting. Are there any types of characters, or any genres that you would like to explore in the future?
Recently, I finished filming a Korean film called Hope, and I played a police officer in a small town. It was my first time trying out a character like that, and I had a great time filming it. I really enjoy trying new things, and I find it very exciting to attempt roles that I have no experience with. Nothing is set in stone right now, but one day, I’d love to do a romance series.
