If you’ve ever wondered about the importance of the sort of photographs that have come to be known as “graphic,” and thought that they might actually be important to the body politic, there’s a movie you should see.

Journalist Clare Hammond interviews participants at this year's festival of literature and thought, Books, Borders & Bikes, including controversial historian David Starkey, Palestinian surgeon Dr. Izzeldin Abuelaish, and war correspondent Marie Colvin.

This year's Books, Borders & Bikes, at Traquair House, has a star-studded line-up, including David Starkey and Mariella Frostrup.

Borders audiences, it transpired, were quite prepared to find out more about Zimbabwean culture, Palestinian landscape and identity, or what it's like to spend ten years in a Turkish jail for daring to speak Kurdish. Nearly all the events in the tent were packed out, and those that weren't were 90 per cent full. Meanwhile, in Edinburgh, Do We Look Like Refugees?, one of three plays on the Fringe backed by Muller's Beyond Borders organisation, won a Scotsman Fringe First and has gone on to a successful run at London's Riverside Studios. So this year his plans are even more ambitious. In the middle weekend of the Edinburgh Book Festival he has put together a programme so good that it even stands comparison with Edinburgh's own.
