After three decades soaring as an unorthodox visionary, Pharrell Williams is prepared to share the narrative behind his journey to cultural prominence.

"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.
