The Cast of 'All the Light We Cannot See': Your Guide

Netflix's latest historical drama is a story of perseverance and community among the dark days of World War II. All the Light We Cannot See, the streaming giant's adaptation of Anthony Doerr’s Pulitzer Prize-winning novel by the same name, takes place primarily in the French seaside town of Saint-Malo, where a young legally blind woman named Marie-Laure LeBlanc (Aria Mia Loberti) broadcasts a radio show despite such programs being forbidden. As the series unfurls her life in Nazi-occupied France, the series also follows Werner Pfenning (Louis Hoffman), a young German soldier who's tasked with tracking down illegal broadcasts. As American soldiers began their operation to liberate Saint-Malo, Marie and Werner's fates become intertwined via an unknown connection as well as a shared faith in humanity.

To bring the beloved novel to life, director Shawn Levy (of Stranger Things fame) gathered an international cast of both acclaimed, prolific actors and rising newcomers, led by Loberti making her screen debut. Read on to meet the stacked cast of All the Light We Cannot See.

Her most prized possession which makes the journey? A radio, on which she listens to a children's science program narrated by "The Professor."

Before landing her debut role in All the Light, Loberti—a 29-year-old actress and academic from Rhode Island—graduated with a her triple major in philosophy, political science, and communication studies in 2020, and went on to study in the UK as a Fulbright Scholar.

In an interview with Marie Claire, she said of her rising fame, "I’m in a position where I’m representing people who have been voiceless and unrepresented for hundreds of years in the media. It’s intimidating, but I can finally open so many doors. I never had someone like me to look up to."
