Daniel Radcliffe, Rupert Grint and Emma Watson join filmmaker Chris Columbus and other esteemed cast members across all eight Harry Potter films as they travel back to Hogwarts for the first time to celebrate the anniversary of the franchise’s first film, Harry Potter and the Sorcerer’s Stone, which premiered 20 years ago.
The retrospective will tell an enchanting making-of story through all-new in-depth interviews and cast conversations, inviting fans on a magical first-person journey through one of the most beloved film franchises of all time.

Did China hide crucial information about Covid-19 from the world? What began with a handful of mystery pneumonia cases in Wuhan late last year has now left more than half a million dead worldwide. Beijing says it has been open and transparent throughout, but former BBC China Editor Carrie Gracie investigates how it delayed reporting the initial outbreak and evidence that Covid-19 could be spread by people. It also silenced doctors who tried to speak out.
The film also hears from one high-level insider who believes the animal market at the centre of the Wuhan outbreak should have been treated as a 'crime scene' and from experts who warn that this crisis may be a 'dress rehearsal' for an even more deadly pandemic in the future.

This documentary tells the story a young polar bear's epic migration through the icy waters of Hudson Bay and his subsequent adventures on land, where he must spend the ice-free season. It is his first summer alone without his mother to guide and feed him. His struggle to survive is set against the biggest environmental story of our time: climate change. The stunning images were taken with more than eight different kinds of cameras including, for the first time, a polar bear collar-cam; a remote control Truck-cam; a mini Heli-cam, and several underwater cameras.

More than a decade ago, scientists announced that they had produced the first draft of the human genome, the 3.6 billion letters of our genetic code. It was seen as one of the greatest scientific achievements of our age, a breakthrough that would usher in a new age of medicine. Find out how close we are to developing the life-changing treatments that were hoped for". Follow three people, each with a genetic disease, as they go behind the scenes at some of Britain's leading research labs to find out what the sequencing of the human genome has done for them - and the hope this remarkable project offers all of us.

Mysterious lights shine out from the edge of space, brighter than a trillion suns. They had to be the brightest objects we've ever seen in the universe, putting out amounts of energy that we couldn't possibly explain. So powerful, they can incinerate planets and rip stars to pieces. These are among the most mysterious and most energetic phenomenon in the universe. They can destroy galaxies, but may also be the key to their survival. These objects are a hotbed of all kinds of crazy physics. These celestial powerhouses are called quasars, and we may owe them our very existence.

Trailblazing scientists are making ground-breaking discoveries in the rapidly evolving world of genetic engineering. Technologies like CRISPR are making it possible to quickly and cheaply change the DNA of all living things, including humans. Today, genes can be edited almost as easily as words on a computer screen. This new ability to alter our DNA holds the promise of curing disease , saving threatened species, solving the problem of world hunger and maybe even obtaining human perfection. But will the promise be fulfilled and at what cost?
The ability to gain control of our DNA is ground-breaking and revolutionary but there are varying opinions among scientists as to how the technology should be used responsibly. This documentary follows the science as it progresses at a breakneck speed.
