You’re starring in The Karate Kid – The Musical at New Wimbledon Theatre. What can you tell us about the show?
The thing that surprised me the most is how emotionally moving it was and how much heart the piece has. When I initially got the call about auditioning, I raised an eyebrow at another film adaptation, but as soon as I heard the material, I was in and wanted it.
Drew Gasparini’s score is incredible and so authentic. That, combined with a feel-good story and a clever script, means I think this show is going to surprise people a lot with how much soul it has.
You play Lucille LaRusso, a character known to fans of the original film. How have you approached bringing this role to the stage?
I am a huge fan of the movie. It’s a big memory from my childhood. Everyone championed the underdog Daniel, and I always loved Lucille’s energy and comedy.
I have watched the movie again, paying attention to Randee Heller’s performance. She gave Lucille so much sparkle, and I’m trying to capture that same fun, bubbly energy. I never stop moving throughout the scenes, which really helps bring her to life on stage.
What’s great about musical theatre is that we get to learn so much more about Lucille and other characters too. Her past, her struggles, her ambitions, her fears. I’m loving finding her and building the character even further.
This musical is based on such a well-loved film franchise. What do you think makes this stage adaptation resonate with both long-time fans and new audiences?
I think the story of the underdog and his fight for justice and recognition is timeless, and also very resonant right now with everything that’s going on in the world. Daniel’s story is inspiring.
 
 
 
 
It’s a feel-good story about someone fighting for their place in the world and for their voice to be heard. That’s something that connects with all age groups, whether it’s parents who originally loved these characters or children trying to find their own voices.
The production explores themes of mentorship, resilience and balance. Which of those ideas feels most present for you while performing this show?
I feel that, particularly playing Lucille, there is a really strong theme of resilience throughout her storyline. She’s not had it easy. She works hard and tries to make the best of every situation and see the positive.
It’s about that constant need to be your own best friend and your own hype person, to keep going and keep chasing dreams. She uproots her family to move to the opposite coast and start a brand-new life with no support. That takes courage and belief.
You’ve had an extensive career across the West End and international tours. How does The Karate Kid – The Musical compare to other projects you’ve been part of?
I’m so lucky that I’ve had the opportunity to be part of two original casts in my career – The Commitments and Bat Out of Hell. Those are the moments you dream about as a performer, especially in this industry, where you actually get some input into a role and have some space to make creative choices.
I’m really enjoying this journey on The Karate Kid for the same reason.
What would you say to anyone thinking of booking to see The Karate Kid – The Musical?
Do it. You’re going to go on a nostalgic journey filled with love and laughter, and some wonderfully poignant moments. I promise you will leave smiling and feeling exhilarated.
Let this show restore your faith that the good guys win. It’s such an uplifting piece of theatre.
