The Making of AT-AT Day Afternoon by Patrick Boivin
You've seen the full "AT-AT Day Afternoon" by Patrick Boivin HERE, now see the "Making Of" the short, utilizing "Dragon Stop Motion", as well as a "Pink Screen"? Patrick mentions: "If you wanna know why I used a "pink screen", the reason is that I didn't have a green fabric large enough for the toy."
*Awesome*
