Behind the Scenes: Motion Picture Sound Design

Michael Coleman's channel on vimeo has a great collection of behind the scenes footage and interviews for quite a lot of major motion pictures. An often slightly overlooked aspect of filmmaking (in the general public's eye) is nicely brought into focus by this ongoing series under the name of "SoundWorks Collection".

They can also be found at Soundworkscollection.comBe warned though, I lost an afternoon to these!
