In 1862, Charles Darwin faced his greatest dilemma-whether or not to go public with his incendiary theory of evolution. It was a turning point for him, and for science as a whole. Today, scriptwriter John Goldsmith, former head of the British Writer's Guild, has crafted the story into a two-hour special for NOVA. In this interview, he talked to NOVA's Susan Lewis about the challenges of making of the film, and his fascination with the Darwin family.Podcast produced by David Levin. Interview by Susan Lewis.
