It's amazing what you can find when you get off the couch and walk through the toy black-markets. We found the Ultra Build Darth Vader while walking through St. Francis Square in Ortigas. He was just sitting there and we thought "That's cool"
A few days after shooting it, we chanced upon a review of the orginal SirToys Star Wars Ultra Build Darth Vader on YouTube via BensCollectibles. Ben referred to his Ultra Build Darth Vader as being a part of a cancelled line of Star Wars figures that included Boba Fett, C3-P0 and the Imperial Storm Trooper. JC Gold on the comments section of Ben's Youtube page said "This was a fan project on Lego Cuusoo ( now Lego Ideas) and Lego rejected the idea because they did not have the right to make Star Wars action figures. " So not only is this a knock-off, it's also illegal :)
Here's the thing, based upon Ben's review, this Knock-Off is actually better than the original SirToys Ultra Build.
