Now here is an little interesting video about the special effects for The Hobbit: An Unexpected Journey. It must be admitted that the movie's special effects were fantastic. This is about all the hard work put into creating amazing works of art like this. One of the examples from the video are the three trolls: Bert, Tom, and William. They are completely CGI, but three actors and motion-capture was used. The other subjects the video addressed were Gollum and the goblins, but you don't need me to tell you about it! Watch the video for yourselves!
