These are three names no one would ever usually have any reason to put together but yet here they all are, in a landmark documentary together about the conservation efforts of Queen Elizabeth.

Called The Queen’s Green Planet, it will see the monarch have a one-to-one chat with veteran broadcaster and naturalist David Attenborough in her garden in Buckingham Palace, while Jolie, along with her children, also appear in the film. Princes William and Harry are also present.

The film, produced by ITN Productions, will explore the monarch’s new initiative to create a vast network of native forests across Britain and the Commonwealth called the Queen's Commonwealth Canopy.

ITV’s Controller of Factual Jo Clinton Davis said that The Queen’s Green Planet demonstrates how the ambitious global project has spread across more than 50 countries. "Rare is the project that starts as a finite one hour documentary and ends up generating the momentum for a timeless campaigning event," she added.

Watch the trailer below.

The Queen’s Green Planet airs Monday 16th of April at 9pm on ITV (hopefully not too much longer after on TV3).
