This may be the one of the most important Horizon films of recent years. Climate scientists have just discovered a phenomenon that threatens to disrupt our world. It may already have contributed to the deaths of hundreds of thousands through drought and famine. Unchecked, it will strike again. The good news is that there is a cure. The bad news is that the cure may be worse than the disease. If they are right, then in tackling the one problem, we may unleash a climate catastrophe on our planet. This is a film about stark choices and about the dawning realisation that all our predictions about the world's climate may be completely wrong. At its heart is something that scientists are calling "global dimming".

David Attenborough has a passion for birds' eggs. These remarkable structures nurture new life, protecting it from the outside world at the same time as allowing it to breathe. They are strong enough to withstand the full weight of an incubating parent and weak enough to allow a chick to break free. But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Piece by piece, from creation to hatching, David reveals the wonder behind these miracles of nature.

From the imposing mating call of the red deer and the flight of the buzzard to the hunt of the fox and the micro-ecosystem on a massive oak: nature documentarist Luc Enting recorded it all for his stunning feature film Wild Heart of Holland, produced by PVPictures. The result of his efforts is an exciting, moving and often humorous film, revealing the beauty and diversity of this wild park in every season. We also watch the main characters grow up to adulthood, a path inevitably dogged with challenges. Enting: “To me, this park, in any season, has an almost un-Dutch beauty. It is the largest continuous nature reserve in northwest Europe with an incredible variety of landscapes and life. It has forests, heath, sand drifts, brooks and pushed moraines. With my film, I would like to give a new insight into its incredibly diverse nature.”

Hippos and crocs have lived side by side for millennia, but are they cozy bedfellows or arch-enemies? One is a hefty herbivore, the other is the most successful freshwater predator on the planet, so how do they manage to survive together in the same habitat? They each have a unique arsenal of attributes honed by centuries of evolution; muscle power, bite force and ferocious dentition give them the edge in their environment. But once a year, their peaceful semi-aquatic existence turns into a battle for survival.
