Anya Taylor-Joy was a strict “Harry Potter” fan as a child, but now, after being cast in “The Lord of the Rings: The Hunt for Gollum,” she is ready to immerse herself in the world of JRR Tolkien.

“I’m actually about to read the books now,” Taylor-Joy said. Variety on Monday night’s premiere of Apple TV’s “Lucky.” “So when I was a kid, I had the misconception that you could only be a ‘Harry Potter’ fan or a ‘Lord of the Rings’ fan. Nobody told me that. I came up with it on my own. Luckily, during all of COVID, I watched all of ‘The Lord of the Rings’ and it turns out you can love both, and you should.”

When asked about her initial reaction to being cast in “The Hunt for Gollum,” Taylor-Joy said, “It’s really fun. I mean, if my tombstone can say ‘Deadly Elf,’ I feel like I did a good job on this planet. So yeah, I’m excited.”

In June, it was revealed that Taylor-Joy would be joining “The Hunt for Gollum” as Seren, a Sindar elf from the Forest Kingdom, who is described as “a deadly and trusted agent of King Thranduil.” She joins “LOTR” newcomers Kate Winslet, Leo Woodall and Jamie Dornan. Dornan will take on the role of Aragorn from Viggo Mortensen.

Directed by Andy Serkis, who will also reprise his role as Gollum, the film follows Aragorn during the time between “The Hobbit” and “The Fellowship of the Ring,” during which he searched for the ring-obsessed creature. Ian McKellen (Gandalf), Elijah Wood (Frodo) and Lee Pace (King Thranduil) are set to return.

Despite being replaced by Dornan, Serkis recently said on the “Happy, Sad, Confused” podcast that Mortensen is “delighted” with directing the film.

“I don’t really want to get into it now because I want to save it for, you know, later,” Serkis said. “I’ll spare you any discussion about casting. Other than that, we’re thrilled that Jamie is doing it. I mean, we’re, you know, we’re absolutely thrilled. And, by the way, so is Viggo.”
