Beloved detective Nancy Drew is returning to TV - but she'll look different from how fans remember. American network CBS is pledging that the new Nancy Drew won't be white. At the Television Critics Association press previews last week, the head of the CBS entertainment division, Glenn Geller, told reporters his network wanted to focus on diversity, including shows designed around characters who were black and Latino. "We're not casting colour-blind, we're casting colour-conscious," he said.
