After months of breathless speculation, Warner Bros. and New Line have revealed the cast for Lord of the Rings: The Hunt for Gollum. The announcement was tied to the Warners CinemaCon presentation Tuesday evening.

Among the new additions to the cast are Jamie Dornan, who will play Strider, the chief of the Northern Dnedain Rangers and also known to fans as Aragorn. He steps into the shoes of Viggo Mortensen from the original Lord of the Rings trilogy.

Leo Woodall will play Halvard, another of the Dnedain, who is joining Strider on the dangerous hunt. Lee Pace is also back as Thranduil after playing the elf in the Hobbit trilogy.

Lord of the Rings: The Hunt for Gollum has Andy Serkis directing the film and reprising the role of Gollum the tragic figure he originated in Peter JacksonsLord of the Ringstrilogy in the early 2000s and which he returned to inThe Hobbit: An Unexpected Journey.

Across two trilogies, a mark of a Middle-earth film, has always been the formidable array of talent brought to bear in every role.The Hunt for Gollum continues in that tradition, and I am delighted to announce the return of two of Middle-earths most beloved performers, alongside some exceptionally talented new additions to Tolkiens world, said Serkis in a statement.

The Hunt for Gollumtakes place betweenThe Hobbittrilogy andThe Lord of the Ringstrilogy, with Aragorn and Gandalf searching for Gollum to learn more information about Bilbos ring which turns out to be the One Ring that threatens all of Middle-earth during the events ofLord of the Rings.

Kate Winslet is on board as a new addition to the franchise, with Ian McKellen set to return as Gandalf. Elijah Wood is also back as Frodo for the film, which is set for a theatrical release on Dec. 17, 2027. Before Dornans casting announcement, Serkis previously confirmed that the role of Aragorn would be played by a new actor in his prequel.

Its not the only Lord of the Rings movie on the horizon either, as Stephen Colbert is writing a second film alongside Philippa Boyens and Peter McGee, under the working titleThe Lord of the Rings:Shadow of the Past. That movie will come after Hunt for Gollum and does not yet have a director attached.
