These three actors have been very busy. This is the fifth video I've posted that has concerned them. In this particular interview, they discuss how The Hobbit: The Desolation of Smaug will be much darker in tone and story line than The Hobbit: An Unexpected Journey. This is actually another part of the interview done by Yahoo! Movies UK & Ireland, hence the topic overlap with the previous post.
