Piece by Piece review – Pharrell Williams biopic told in Lego is a bit of plastic fun

A documentary portrait of the American music producer and fashion impresario Pharrell Williams, told through the medium of Lego block animation. What at first seems like a quirky gimmick actually works rather well. It’s a fun watch, and the technique allows film-maker Morgan Neville to visually represent Williams’s form of synaesthesia, which turns music into colours, and to explore his musical process in a suitably playful and creative manner.

The cynical may observe that the medium also allows Williams to build a Lego brick wall between Neville and the parts of his life and career that his subject would prefer not to discuss, so don’t go into this expecting anything other than a shiny plastic hagiography.
