Kavenagh’s previous credits include The Picnic at Hanging Rock, BBC mini-series The Cry and Australian TV series Romper Stomper. She’ll play a character named Tyra in the show, though further details of her role have yet to be disclosed.

There’ll likely be no shortage of acting talent vying for a spot in the highly-anticipated LOTR series. The fantasy production is expected to be the most expensive TV show in history; Amazon Studios spent $250 million alone securing the rights for the story from the Tolkien estate. Earlier this month, Amazon signed on Spanish director J.A. Bayona to helm the first two episodes of the series. Star Wars: Beyond writers JD Payne and Patrick McKay are on board to write and serve as co-show runners. Bryan Cogman, a former Game of Thrones writer, has signed on as a consultant. Further details about the show — including specifics about the plot — are scant. Amazon Studio’s Jennifer Salke told THR that the show isn’t expected to begin production until 2020, so fans will have a long wait to hear more.

“J.R.R. Tolkien created one of the most extraordinary and inspiring stories of all time, and as a lifelong fan it is an honor and a joy to join this amazing team,” said Bayona in a statement to Deadline. “I can’t wait to take audiences around the world to Middle-earth and have them discover the wonders of the Second Age, with a never before seen story.” Bayona will be tasked with bringing to life a screenplay by writers JD Payne and Patrick McKay. Even though Bayona is only directing the first two episodes, his work will lay the groundwork for the entire series.

Nearly 16 years after Peter Jackson concluded his genre-defining LOTR trilogy with The Return of the King, Amazon Studio’s upcoming TV series has set out to outdo the 2000s-era films in terms of scope and budget. Instead of a straight rehashing of the J.R.R. Tolkien trilogy, the show will “explore new storylines preceding The Fellowship Of The Ring.” At an expected $500 million for the first two seasons, the show’s budget is twice that of all three Jackson films combined, and is likely to be the most expensive TV production of all time. In a post Game of Thrones world, Amazon is setting high expectations for the LOTR series and hopes to rival the mammoth HBO hit. Given that it’s paying top dollar and drawing in high-caliber talent for this Middle-earth drama, it’ll likely fulfill that goal.
