I wasn't sure what to expect with this tour, but I was pleasantly surprised how much detail there was. They really went all out. It didn't feel at all like the remnants of a film set; more like an active film set or a real place.
In order to make a tree look 60 years younger than the one in the first movie, this one was built. Apparently after they finished attaching all the leaves, they had to take a break from filming. When they came back, the leaves had faded. So they painted each leaf. Thousands and thousands of them.
