Many of the expected conventions of music biopics are present in "Piece by Piece," about the producer-turned-pop star Pharrell Williams, and "Better Man," about the British singer Robbie Williams. There's the young artist's urge to break through, fallow creative periods and regrettable chapters of fame-addled excess. But there are a few, little differences. In "Piece by Piece," Pharrell is a Lego. And in "Better Man," Williams is played by a CGI monkey. If the music biopic can sometimes feel a little stale in format, these two movies, both premiering this week at the Toronto International Film Festival, attempt novel remixes. In each film, each Williams recounts his life story as a narrator. But their on-screen selves aren't movie stars who studied to get a part just right, but computer-generated animations living out real superstar fantasies. While neither Williams has much in common as a musician, neither has had a very traditional career. Their films became reflections of their individuality, and, maybe, a way to distinguish themselves in the crowded field of music biopics like "Bohemian Rhapsody" and "Rocketman."

A wide spectrum of things you never expected to see in Lego form are animated. Virginia Beach (where Pharrell grew up). An album of Stevie Wonder's "Songs in the Key of Life."... Read More
