It's the fifth year of World War Two and the Nazis occupy France; in the coastal town of Saint-Malo, a collection of French and German characters are all about to find their fates irrevocably linked.

This is the premise of All The Light We Cannot See, a new four-part period drama on Netflix that is based on an award-winning Anthony Doerr novel of the same name.

All The Light We Cannot See has some legacy actors but also introduces Netflix fans to a few brand-new faces who have never received an acting credit before in their lives. So it's a very varied cast.

So which of these is which? Well, let's meet the cast of All The Light We Cannot See, to get to know the five most important characters.

Aria Mia Loberti as Marie-Laure LeBlanc

Marie-Laure LeBlanc is a French girl who's been blind for at least 10 years now. She's well-versed in the layout of her home town, Saint-Malo, and is also very good at reading people based on their voice. However, her family ties mean she's always very close to danger.

Aria Mia Loberti plays Marie-Laure, and the woman is a newcomer to the screen. Like her character she's blind, though she is not in fact French. Loberti was reportedly a fan of the book before casting began, and beat thousands of other submissions in order to get the leading role.

Nell Sutton plays a younger version of Marie-Laure, and it's also her first credit.

Louis Hofmann as Werner Pfennig
