BBC News: Is Will Smith too light for this role and why does it matter?
"Earlier this week, it was reported that Will Smith could be starring in a new project called King Richard, telling the story of Richard Williams, the father of tennis icons Venus and Serena Williams.
While Smith has yet to confirm the news, it didn't stop fans from tweeting their excitement about the idea of the star portraying such an accomplished man.
But there were a few who weren't so pleased with the choice, and not because they were questioning the star's talent, but because his skin tone isn't considered dark enough.
In recent years, Hollywood has made progress in representing minorities on screen, yet we still find ourselves circling around the issue of colourism."
