When you look at the way Hollywood discovers talent, every so often a young actress comes along who feels instantly familiar and excitingly new. Olivia Marcum is one of those names. She may still be early in her career, but there’s already a sense that she’s someone we’ll be talking about for years to come.
Early Spark and Biography
The first thing that makes Olivia Marcum stand out is her story. Though the details of the ‘Oliva Marcum biography’ are still being written, what’s clear is that she has that magnetic quality where you notice her among all the new faces that come around.
Olivia seems to be a natural.
Like many rising stars, she started with smaller projects that gave her room to experiment. Before making her mark on the big screen, Olivia was stage-trained and had a flourishing background in musical theatre. She first caught attention playing the title character in Matilda: The Musical, and also appeared in a production of Chitty Chitty Bang Bang.
The Breakthrough Role
Every career has a turning point, a project that suddenly shifts the way audiences and critics look at an actor. For Olivia Marcum, that breakthrough role was The Exorcist: Believer (2023). She landed her feature‑film debut: the haunting, tricky role of Katherine, one of the two girls possessed in the film directed by David Gordon Green.
When you watch her performance in The Exorcist: Believer, you can still sense the young actress who was once exploring her craft under the spotlight of musical theatre. It’s the same curiosity and the willingness to take risks that shine through even now. That’s the kind of skill that makes casting directors pay attention.
A Young Actress on the Rise

You look at her stage roots in Matilda: The Musical and Chitty Chitty Bang Bang, and you see the kind of foundation that turns raw talent into real craft. Those productions are no small feat, and Matilda, in particular, requires a young actress to command the stage night after night, balancing wit, energy, and vulnerability. That’s training you can’t fake.
Then comes The Exorcist: Believer. For Marcum to step into a franchise with that kind of history and in her very first feature role says a lot about the confidence filmmakers had in her. And the fact that she didn’t just fade into the background but became one of the most talked-about parts of the film says even more. That’s not hype—that’s range.
