The hit-making producer goes deep on the concept of gratitude, his relationship with Chad Hugo and capturing his life story — in Lego form — with the help of director Morgan Neville.

“Piece by Piece” is a bright, clever song-filled biopic that pretends it’s a behind-the-scenes documentary using small plastic bricks, angles and curves to celebrate an artist known for his quirky soul. It is deep and surreal and often adorable. Is it high concept or low? Like Williams, it’s a bit of both.

A movie documentary that uses only Lego pieces might seem an unconventional choice. When that documentary is about renowned musician-producer Pharrell Williams, it’s actually sort of on-brand.
