We know that Cate Blanchett (Galadriel) is in New Zealand, and thanks to Mr. Tadpole we know she’s been on set recently:
Filming is occurring at Fernside Lodge, a large homestead about 4km out of Featherston. It’s a stunning location, absolutely gorgeous, that people often hire out for big fancy weddings. Click on the ‘Gardens’ link to get an idea of the scenery they’re shooting in, particuarly the Fern Gardens.
Xoanon here: Judging from the beauty and look of this location, add to it the rumors about seeing Craig Parker (Haldir) on the set as well, it only seems right that the set is Lothlorien, home to Galadriel and the Elves.
