Louis McCartney Steps into the Spotlight: From Sullivan to Broadway and The Tonight Show

At Sullivan Connect, we take immense pride in watching our alumni chase dreams, break boundaries, and share their talents with the world. This month, we are celebrating an extraordinary moment in the journey of one of our own — Louis McCartney, who recently made his Broadway debut in Stranger Things: The First Shadow and appeared on The Tonight Show Starring Jimmy Fallon to discuss the experience.

For many, stepping onto a Broadway stage is the pinnacle of a performer’s journey. For Louis, it’s only the beginning of what promises to be an extraordinary career. Cast in the highly anticipated theatrical prequel to the hit Netflix series Stranger Things, Louis takes on a leading role that is already earning him praise from critics and audiences alike. The show, set in the mysterious town of Hawkins in the 1950s, has become a theatrical event — and Louis is at the centre of it all.

On The Tonight Show, Louis brought charm and humility to the national stage as he shared what it was like stepping into such an iconic universe. From audition nerves to opening night jitters, and the surreal experience of working with theatre legends, Louis gave viewers a behind-the-scenes glimpse into the world of Broadway — and the hard work it takes to get there.

His story is one of talent, determination, and the kind of quiet confidence that can only come from staying true to your craft. It’s also a powerful reminder of the community that helps shape a performer. At Sullivan, Louis was known for his dedication, his curiosity, and the spark he brought to every performance. Seeing him shine now, we are not just proud — we are inspired.

As Louis continues to climb, we will be cheering him on every step of the way. His success is a testament to the power of believing in your dreams, and the importance of the support systems that lift you up along the way.

Congratulations, Louis — Broadway looks good on you.
