The extraordinary physical and mental demands of performing Sichuan opera

With origins deep in southern China’s folk storytelling and music customs, Sichuan opera is characterised by traditional instrumentation, a distinctive singing style, elaborate, colourful costumes, changing masks that reflect characters’ emotional states, and daring stunts including martial arts, acrobatics and fire-breathing. Part of a video series on work in modern China by the US filmmaker Noah Sheldon, this short documentary profiles the Chongqing-based Sichuan opera singer Zhou Xing Yu as she prepares for her next show, reflecting on her abiding love of performing despite the intensity and pain of many years of training.

A curtain that twitches as people walk by creates a delightful paradox of privacy

In 2010, the German artist Niklas Roy embarked on a project to take back a small slice of privacy in an era and in a place – his Berlin workshop – where it can be quite hard to come by. The resulting installation, My Little Piece of Privacy, comprised a surveillance camera, ‘computer vision’ software and a small, motorised curtain, which followed pedestrians as they walked past his storefront. As you might imagine, the moving curtain had an inverse (and amusing) effect, causing passersby to spend far more time in front of his window than they would have otherwise. This short video, featuring scenes from the installation set to a retro arcade-inspired score, makes a highly entertaining spectacle out of Roy’s clever provocation of privacy.

Climate change science is centuries, not decades old, and it was pioneered by a woman

The notion that human activities might be warming the planet started coming into focus in the 1960s and ’70s, before a scientific consensus emerged in the 1980s and ’90s. But the rough outlines of the science surrounding humanity’s greatest contemporary threat has a surprising, little-known history that dates back roughly two centuries. This brief animation from BBC Ideas traces our modern understanding of the greenhouse effect through the work of three pioneering scientists, beginning with the US scientist and women’s rights activist Eunice Foote, whose 1856 work on the heat-trapping effects of CO₂ was buried for decades before being rediscovered in 2010.

After 30 years of solitude, Peter forms an unlikely friendship with a fellow loner

‘I had left my flock, and Ben had left his.’

After taking a walk through a remote Welsh valley, Peter committed himself to a life there, and disconnected from the outside world. In doing so, he found a solitary inner peace – a peace he maintained for nearly three decades, until, one day, he stumbled upon a lamb that had been left for dead. Finding kinship with the fellow ‘dropout’, Peter took the abandoned creature home and named him Ben. The short Peter and Ben (2007) by the UK filmmaker Pinny Grylls captures the duo’s relationship three years after their chance meeting, as Peter attempts to return Ben to the wild. With a melancholic piano score and sweeping views of the Welsh countryside, her touching film lends a lyrical beauty to this tale of unlikely connection and camaraderie between outsiders.

Trawling for secrets in haunting films recovered from the bottom of the sea

The British ocean liner RMS Lusitania embarked on its infamous final voyage from New York to Liverpool on 1 May 1915. Six days later, torpedoed by German U-boats off the southern coast of Ireland, the ship sank in less than 20 minutes, killing 1,198 passengers and crew, and setting the US on the path to join the fight against Germany in the First World War. One of the most luxurious ocean liners of its time, the Lusitania was equipped with what was then a novelty – an onboard movie theatre.

In Sunken Films, the US artist and filmmaker Bill Morrison uses archival footage to unspool the stories of the sinking of this luxury liner, its incendiary movie reels, as well as other films about or from shipwrecks. One early clip was salvaged from the sunken Lusitania in a 1982 expedition; another mysterious film, featuring the Russian revolutionary Vladimir Lenin in 1919-20 with his cat, was recovered from a fishing net off the Danish coast in 1976. By trawling for memories in deep-sea shipwrecks, Morrison offers haunting glimpses into early-20th century film and world history.
