This year marks the 50th anniversary of the release of landmark wildlife film Born Free, starring Virginia McKenna and her late husband Bill Travers as real-life couple Joy and George Adamson, who raised an orphaned lion cub, Elsa, and successfully released her back into the wild.

This beautiful documentary sees Virginia and her eldest son Will – who was five when Born Free was made – return to Kenya for the first time together to retrace how this charming and dramatic story was brought to the silver screen, and how it led them to set up the Born Free Foundation conservation and animal rights charity.
