The workers at the smart Borusan Holdings head office are expected to be tidy, especially on a Friday. That’s because their office doubles up as an art gallery, the Borusan Contemporary, at weekends. There are some paintings, like the attractive wall paintings of Jenny Zenuik, although the main thrust of the collection is up-to-the-minute electronic art. Some seem a little gimmicky, like superior executive toys, such as one where you place your finger in a hole and the frame turns into images of your fingerprint, but it’s an excellent way to pass an hour or two.

A police procedural played out over a long dark night of the soul, Once Upon a Time in Anatolia is the magnificent sixth feature from Turkish writer / director Nuri Bilge Ceylan (Three Monkeys, Uzak). So much more than a simple thriller, it transforms a murder investigation into something gratifyingly profound and perversely beautiful; its grizzled, largely unfamiliar faces and their tales of woe will remain with you long after the end credits roll.

One of the highlights of this year’s Brighton Festival, curated largely via web chats and long-distance phone conversations by Aung San Suu Kyi, is Kutlug Ataman’s silent film installation Mesopotamian Dramaturgies. The leading Turkish artist, a favourite of international biennales and arts festivals, has taken over the town’s Old Municipal Market to show two multiple-screen works. And in this vast, disused space, as gloomily dark and dank as it is cavernous, we find the perfect backdrop against which Ataman’s films shine.

As a child I lived for a while near the footings in Ortaköy of the Bosphorus Bridge, which was being constructed over the breathtaking straits of Istanbul. Our life as oil expatriates was many worlds away from the skinny hawkers, whistling traffic cops and sweating construction workers whom our car passed every day. Four decades later this magnificent bridge has brought a global political metaphor, an entire little commercial ecosystem, and a raft of deeply affecting human existences.

Collaborations for dance, theatre and other things are coming thick and fast at Sadler’s Wells nowadays - these are not halcyon days for pure choreography.
