The BBC recently announced that my new film ‘Touched by Auschwitz’ will be broadcast in January 2015 as part of a season commemorating the liberation of Auschwitz 70 years ago.

I’ll write more about the film – a 90 minute feature length documentary – once I know an exact transmission date. All I’ll say now is that it’s been the most astonishing privilege to travel around the world and film with so many survivors of Auschwitz and their families.

Ever since I made the six part series ‘Auschwitz: the Nazis and the ‘Final Solution” ten years ago I’ve wanted to make a film about what happened to survivors after their liberation. My previous work has been almost exclusively about the wartime years, but I was always aware that there existed the most incredible story to tell about the challenges that survivors faced on their release from the camps.

It’s a story of individuals that also encompasses world changing events – like the formation of the state of Israel. It’s also a history that’s full of surprises. The children and grandchildren of Holocaust survivors, for instance, have the most fascinating things to say.

But it’s the survivors themselves who take center stage. And what they say about how Auschwitz has affected them will stay with me for the rest of my life.
