Hollywood couple Uma Thurman and Ethan Hawke are tipped to be part of The Lord of the Rings when cameras begin rolling in Wellington on October 11.
Sian Clement, a spokeswoman for film-maker Peter Jackson, said while casting was still being finalised filming would start in less than two months at Jackson's Camperdown Studios in Miramar.
New Line Cinema president Michael Deluca, whose company is backing the trilogy, said it was negotiating with a husband-and-wife team for the roles of Galadriel and Faramir.
Thurman and Hawke, both 29, married last year after meeting on the set of Gattaca, which was directed by Paraparaumu-born screenwriter Andrew Niccol.
Thurman is best known for her role in Pulp Fiction, while Hawke has starred in Dead Poets' Society, Great Expectations, and Alive.
Sir Ian McKellen (Gandalf), Sir Ian Holm (Bilbo), Elijah Wood (Frodo), Sean Astin (Samwise Gamgee), and Billy Boyd (Pippin) are among those said to have been signed.
