Much of the doc explores how devotees use the blocks to make art, create huge displays, and even employ them in the name of science (the MIT Media Lab studies city patterns with Legos). But one of the most fascinating segments in the documentary examines how Dr. Daniel LeGoff (yep, "Lego" is in his name) studied the positive effects that the toys had on children with autism. Playing with Legos not only gave the children a creative outlet, but also opened up a social avenue for them.This is kind of a given considering the guy has a song called "Lego House" and a Lego tattoo . But the singer-songwriter, who makes an appearance in the documentary, also reveals that when his record went gold, his first major purchase wasn't a house or a car, but the Lego Death Star. So there you have it, the quickest way to Ed Sheeran's heart is through colorful plastic toys.Back in 2013, Lego built its largest model to date, a life-size, full-scale model of the X-Wing fighter from Star Wars. The massive undertaking — which took a team of builders, mechanics, designers, and developers over 17,000 hours to complete — was created with over 5 million bricks (weighing in at 8 tons). The final product, which was unveiled in Times Square, has a wingspan of 44 feet, measures 5 feet from bow to stern, and stands 11 feet tall. It now lives in the Lego factory in Frankfurt, Germany. (Take note, Ed Sheeran!)
