Though Denis Villeneuve’s Dune is about Timothée Chalamet’s Paul Atreides’ gradual rise to prominence in the galaxy, none of it would be possible without his mother, Lady Jessica.

Played by Rebecca Ferguson, Jessica is the lover of Duke Leto (Oscar Isaac) and more importantly, the member of an order of witches known as the Bene Gesserit, and has been subtly orchestrating events so the Atreides’ journey to the planet Arrakis could be the starting point for an entire galactic revolution.

Though it obviously informed Ferguson’s take on the character, she soon made her own distinct version of Jessica.

That’s an interesting starting point for a character and a journey.”.

The first comes before the Atreides’ journey to Arrakis, where her character doing the Litany Against Fear, an iconic quote that belongs to Paul in the books, but is here given to Jessica instead.

That’s her character for me,” Ferguson said.

The second comes at the end when Paul and Jessica join forces with the Fremen.
