Symbolic racism is hurtful and it is especially hurtful to Black children who get called Black Pete in school and grow up with the sense that they are inferior to white kids.

There is much institutionalized racism in The Netherlands and the non-White population is just now beginning to fight for their rights.

When I first saw a White Dutch person dressed up as Black Pete, I was both sickened and shocked. It's hard to stand next to someone who views your skin color and hair as a costume. As a filmmaker, whenever I get that feeling, I want to explore what motivates people to engage in such offensive behavior and enlighten folks about its origins.

I both didn't know Owen [Suskind] beforehand and didn't have any connection to the autistic community. But Owen wasn't really a problem, because he participated in the writing of the book and wanted people to see him as he truly is. As far as the cameras, Owen lives in the moment and the cameras really didn't distract him.

I think what was special about 'Music by Prudence' was the classic story of the title subject's life path - from being an outcast in her society because she was disabled, to someone who picked herself from that despair and elevated herself within that community, and now that society accepting her as much as they formerly rejected her. People identified with that journey, overcoming an obstacle, but still triumphing.

The challenge and the goal was to get inside Owen's [Suskind] world, because I really wanted to see it through his point of view. To achieve that naturalism, I used a screen in front of a camera as I interviewed him

I had full access to the material, and had a great relationship with Sean Bailey, the president of Disney productions. He really guided me through the licensing process of the footage. I made presentations to the various departments at the studio, and they were moved by Owen's [Suskind] story.
