An idyllic British river: misty dawns, dancing mayflies, lazy trout and fluffy chicks paddling under the watchful gaze of their parents. "My Halcyon River" is an intimate portrait of a secret world where otters hunt on the midnight current, mink lie in wait to ambush unwary victims and gleaming kingfishers pierce the water to spear their prey. These dramas, both mortal and touching are revealed through the eyes of a man who has loved the river since he was a boy, cameraman Charlie Hamilton-James.

An ancient oak wood in the heart of England is as full of beauty and drama as anywhere on Earth. Philippa Forrester spends a year witnessing its secret life - the sparrow-hawk terrorising blue tits, fox cubs learning to stalk rabbits and a buzzard looking for love.

Filmmakers Charlie Hamilton-James and Philippa Forrester went in search of otters on a short stretch of the River Torridge in Devon, immortalised 80 years ago by Henry Williamson in his famous novel Tarka the Otter. Over months of patient fieldwork they got to know and film a family of wild otters. The result is both a lyrical portrait of these shy creatures and a tribute to Williamson's skills as a writer and naturalist.

Vultures are the birds that many people love to hate, but cameraman and naturalist Charlie Hamilton James sees them as beautiful and intelligent creatures that deserve respect. He believes that to appreciate them, people just need to spend time with them and he headed to East Africa to do exactly that. His journey exposes not only a softer, more caring side to these maligned birds but also a much bigger story, one that leaves vultures needing many more admirers.
