Italian master Caravaggio’s final painting has arrived in London – the first time it’s been in the capital for 20 years. He painted 'The Martyrdom of Saint Ursula' in Naples in 1610. Two months later, he died in mysterious circumstances. But his later years produced some of his most striking works – and this one is right at the heart of the story. Available to view until 21st July, the painting can be seen for free by anyone with a gallery entry ticket to the National Gallery.

Another masterpiece making its appearance in London after decades away is Complicité’s production of Mnemonic, which has returned to the National Theatre 25 years after it received buckets of five-star reviews. A body is found in the ice, and a woman is looking for her father while a man searches for his lost lover. This story is as much about origins as it is about memory, and remembering what is lost. Twenty-five years on, Mnemonic asks: what is our place in the natural world? How have human relationships with the environment shaped patterns of migration? Who are we, and where do we come from? Complicité co-founder Simon McBurney (Drive Your Plow Over the Bones of the Dead, The Encounter) directs.

Gary Hustwit, the director behind excellent design documentaries Helvetica and Rams, has turned his attention to visionary musician and artist Brian Eno. With access to hundreds of hours of never-before-seen footage and unreleased music, Hustwit’s documentary uses ground-breaking technology to accomplish something that’s never been done before: a feature film that’s different each time it’s shown. Eno is the hugely influential British musician, producer, activist, visual artist and self-described “sonic landscaper” who began his career as an original member of the legendary Roxy Music in the early 1970s. He has since released over 40 solo and collaboration records, pioneered the genre of ambient music, and helped define and reinvent the sounds of David Bowie, U2, Talking Heads and Coldplay. Launching on Friday, the film will play in Picturehouse cinemas across the country, with a different version of the film emerging on screen each day.
