Britain’s most distinguished broadcaster and naturalist visited Harrow for an evening of conversation with Alastair Fothergill, an Old Harrovian and renowned producer of natural history documentaries and films. Alastair has worked with Sir David on many of the BBC’s most highly regarded natural history programmes including Planet Earth and Blue Planet. In a series of anecdotes, they recalled some of the most spectacular, dangerous and funny events of their years of collaboration.
