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.

Pharrell Williams is thankful someone took a risk on his brand of unconventional storytelling. At a recent screening of his new animated documentary Piece by Piece, the 13x Grammy winner expressed his gratitude to Lego‘s head of global entertainment Jill Wilfert for saying “yes” and collaborating on the film.
