Sir David Attenborough has been making natural history and wildlife documentaries for more than 60 years. One of his earliest productions, Zoo Quest, was broadcast in the early 1950s, before colour TVs were a household staple. Now, decades later, a BBC archivist has discovered six hours of Zoo Quest footage shot in gorgeous colour. It was a complete surprise because everyone, including Attenborough, had assumed the films were captured in monochrome.
