With Dune: Part Two already in cinemas, Anya Taylor-Joy's mysterious role has finally been revealed. It confirms a major departure from Frank Herbert's 1965 book.

After all, Denis Villeneuve wasn't trying to do a word-for-word adaptation of Dune.

"The idea is to try to be faithful to the author, as much as possible, to his intentions and his poetry. All the decisions were made to try to respect Frank Herbert's initial ideas," director Denis Villeneuve said in an exclusive interview with Digital Spy.

He also offered us some clues explaining that massive change with Taylor-Joy's mysterious character (more on that later.)

Dune 2 sees Paul (Timothée Chalamet) and his mother Lady Jessica (Rebecca Ferguson) fighting off the Harkonnens alongside the Fremen, as the war for Arrakis gets more intense and a long-awaited leader rises from the ashes of House Atreides.

Fans of Herbert's books, or those viewers who remember David Lynch's 1984 film adaptation, will notice there is one notable absence in the cast of Villeneuve's sequel. Here we delve into the story of that character, and what her future holds in the film franchise.

Who does Anya Taylor-Joy play in Dune 2?

In Dune 2, Anya Taylor-Joy takes on the role of Alia Atreides. She is the daughter of Leto Atreides and Lady Jessica, so is Paul Atreides' sister.

However, in the sequel, Alia is not actually born. After Lady Jessica drinks the Water of Life while pregnant, her foetus receives the vast knowledge and foresight of the Reverend Mothers, meaning Jessica can communicate with Alia while she is still in the womb.

Later on, Paul has a vision of his sister.

After also drinking the Water of Life and accessing that heritage of power, Paul sees Alia as a grown woman (Taylor-Joy) standing mysteriously on a beach. She warns him of their family's secrets. "You are not prepared," she tells him.

That's the extent of what we can see of Alia Atreides in Dune 2, which is a major departure from her storyline in Frank Herbert's first book.

In 1965's Dune, Alia is born while Paul and Lady Jessica are still staying with the Fremen in Arrakis' desert, and has a more active role in the final battle.

Since she was exposed to the Water of Life during the pregnancy, Alia is born with the full powers of a Reverend Mother. The Bene Gesserit would call her an Abomination (because a child could be easily dominated by the personalities contained in the Other Memory, the heritage of the Reverend Mothers' ancestors, and become uncontrollable) but Lady Jessica decides to give her a chance to live and control her powers.

Raised among the Fremen, 4-year-old Alia becomes a skilled warrior, though she is captured by the Emperor's forces. In the final battle in Arrakeen, Alia escapes after poisoning Baron Harkonnen with the deadly needle known as the Gom Jabbar.

Back on the battlefield, she kills fallen warriors from the Sardaukar and Harkonnen armies with a traditional crysknife, earning her the name St Alia of the Knife.

Alia Atreides' story continues in the following books (Dune: Messiah, Children of Dune, Hunters of Dune and Sandworms of Dune), but we don't know yet how her journey will develop on the big screen, given the changes in the adaptation.

In an exclusive interview with Digital Spy, Denis Villeneuve explained the reasons why Alia's storyline was changed for the sequel.

He said the decision had been made "to compress time, to put more pressure on Paul, to also create an interesting dynamic with Jessica, to increase this idea that the Bene Gesserit have control over their genetics and control over their bodies.

"And to have those surreal dialogues that I think I've never seen in cinema. Everything has been done, but that I've not seen yet. I was very excited."
