“We want you to see a doctor. You’ve changed, and not in a good way,” says Kathy’s underwhelming husband, Tim (Matthew Jure).

We don’t know what Kathy (Cathy Naden, making her film debut) was like before, but as things stand she seems to be following her impulses gaily and uninhibitedly. In the first scene, we see her chatting to Nick (Jerry Killick), a laid-back, pony-tailed gardener at the museum where she works as an archaeologist. She admires his vintage BMW. He takes her up on her request to go for a spin; then they have sex in the back seat.

We are still acknowledging our 21st-century debts to the energy, curiosity, determination and passion for discovery of a host of Victorian polymaths, and here is another. Sir Charles Eastlake (1793-1865) was a painter, scholar, author, collector and translator – fluent in German, French, Italian – and the first director of the National Gallery, rising above disputes with trustees and the government to set the scene for the role it plays today.

Gleaming, shimmering, full of pizzazz, glitz and unashamed bling, although of the 18th-century sort, as befits its role as the most cheerfully mixed up and glittering show of baubles in Bath, the Holburne Museum reopened in May after three years' closure. At a cost of £11.2 million the museum has been expanded, rebuilt, refurbished and renovated. Much more of the collection, newly installed after extensive conservation, is also on view than hitherto. The whole works a treat. As many visitors have turned up in the first month as normally come in a year.

The Egyptian Government is investing in the arts, which would normally be a cause for celebration. However, in building the National Museum of Egyptian Civilisation, it feels like the country’s cultural budget is being spent on another new display case for its past rather than on encouraging a contemporary arts scene. The NMEC, which was first mooted in 1982 (the year after Sadat was assassinated, if that signifies anything today), will open this year in south-east Cairo, after seven years of construction, nine years since the foundation stone was laid.

Sergei Diaghilev was not short of self-belief. He appointed himself the man to introduce European modern art to Russia and then Russian modern art to Europe as the 20th century began, and in doing so he defined himself as the ultimate artistic director, as the remarkable, tentacular exhibition at the V&A Museum that opened yesterday shows. Reviewed elsewhere on theartsdesk, the exhibition's mounting has thrown up extraordinary inside dramas - the telltale paper found in the boning of a 1916 tutu, the unlikely discovery of a stellar bust in a junk shop, and the legendary artists' sweat that no cleaning can obliterate.

The British Museum’s current exhibition of 15th-century works on paper, Fra Angelico to Leonardo: Italian Renaissance Drawings, explores the increasing importance of the preparatory sketch in the development of western art. Central to that development was the availability of cheaply produced paper.

This superb exhibition of Italian Renaissance drawings, featuring 100 works and chosen from the outstanding graphic collections of the Uffizi and the British Museum, explores the evolution of the preparatory sketch in the 15th century. We learn how artists began to experiment with the medium in order to create finished paintings that were far more compositionally and stylistically ambitious, far more dramatic and full of movement, than anything that had come before. And though the drawings themselves were never meant to be seen outside the artist’s studio, we learn that by the early part of the 16th century, drawing had gained great importance as a medium in its own right.
