The main reasons you really should consider getting The Hobbit: The Desolation of Smaug Extended Edition isn't the extra 25 minutes of scenes but really the best behind the scenes documentary ever made for movies that is collectively called "The Appendices". No other movie does it as well. Below is a clip from the section called "Barrels Out of Bond: The Elven Sluice" that hints at both the very low tech approach (foot powered locomotion) and the high tech (whole lot of CGI) that was part of making the barrel escape sequence. The extended edition will be released on November 4th. To pre-order from Amazon: Blu-Ray + Digital HD | DVD | Blu-ray 3D Amazon Exclusive Set
