People just love making things out of Lego. Release a new trailer; someone will make it out of Lego. Know a famous monument of some kind? Someone will have recreated it with little knobbly bricks. The latest thing that some enterprising soul has plasticised is the shopping mall car chase scene in The Blues Brothers. And it is enormously impressive.
There’s also a ‘making of’ if you particularly want to see how the short film was made. But sometimes, as with magic, it’s just nice to bask in quiet awe at the patience and skill of some people. The world is vastly improved by those with too much time on their hands.
