Kief Davidson and Daniel Junge’s new documentary takes viewers deep into the world of the iconic small plastic bricks, from the toy’s somewhat fiery origins in Denmark to its big-screen incarnation in last year’s The Lego Movie. Some of the material will be familiar to even the casual assembler, but the film finds interesting angles amidst seemingly Mega-Marketing Movie-Tie-In World of Lego. Crazy creativity still abounds among hobbyists, and even Lego sponsors contests for players to come up with new designs. Among street artists, there is such a thing as Lego-bombing. And one Lego enthusiast makes a decent argument that Lego is a universal human language, in which everyone everywhere can, without any instruction, fit two or more blocks together and build something.
