I recently scored this hour-long film for the BBC. It introduces a group of newly-retired female chimpanzees to a US national chimpanzee sanctuary after making the 800-mile journey from a New Mexico laboratory to rural Louisiana. After a lifetime used in medical research, they will now live out their days in beautiful forested surroundings. Sue Perkins guides us through their journey. You can watch this on New Years Day at 9pm, BBC2.
