Right after the tour, I saw the Hobbit at the Roxy Theater down the street from Weta. The Roxy is a 1920s art deco theater restored by Peter Jackson (among others). Some of the design is a little different than your standard art deco.
The Hobbit was shown in 3D HFR (high frame rate), which is double the standard movie frame rate. It’s very different and…weird. I don’t know if it’s something I’d get used to. I thought it gave it a sort of video feel, and some of the backdrops looked really flat, even though I’m pretty sure they were shot on location. The only scenes I thought it enhanced were the darker CGI scenes, such as the ones in the goblin cave.
