Not sure why but more than the usual number of sites posted their interviews with mostly Evangeline Lilly but also with few other actors from The Hobbit: The Desolation of Smaug. Also have a few set reports. Usually this far away from release its one site posting something and the rest then posting about that first post. The timing is weird to me because usually this is the kind of thing you start seeing around two weeks before a movie opens, not two months. It might be worth reading as these questions will eventually be asked hundreds of times by reporters so for now the answers are less sales pitchy, longer and more spontaneous until the repetition results in the short and concise answers normally see.
Evangeline Lilly's interviews are probably the most interesting as she is clearly very enthusiastic about the role of Tauriel and is glad to be able to finally talk about it. I am starting to suspect she is a bit of a closet geek. The One Ring's set visit is also of interest as the writer was an extra on the New Zealand so provides his view of the experience. Worth while as written by a fan living a dream trying to report the experience rather then as a reporter who really isn't a fan and doesn't really care about the subject they cover (like most entertainment reporters).
