VFX documentary- Empire Strikes Back behind the scenes

Perhaps the most highly regarded film in the Star Wars saga is The Empire Strikes Back. This half hour documentary by Michel Parbot  has recently appeared on youtube courtesy of starwarsarchives.com. It allows the viewer some amazing insight into how effects and sets were created in the pre-digital age. It shows the stop motion techniques used to create the AT AT and the Tauntaun riding creatures. You can see matte paintings created on glass as well as set constructions of the Hoth base and the swamp planet of Yoda. It's an amazing time capsule of what it was like when problem solving didn't involve the convenience of computers.
