Harry Potter star Daniel Radcliffe has narrated a Holocaust memorial film marking the upcoming 65th anniversary of the liberation of Auschwitz-Birkenau.

The film, The Legacy of Hope, is being released by the Holocaust Memorial Day Trust, of which Radcliffe, 20, is a supporter. The Jewish actor said he was “privileged” to be involved.

“I felt that in a very small way I was contributing to the remembrance of these tragic and horrendous events, whilst also commemorating all those people who refused to let the horrors they had lived through dictate the tone of the rest of their lives. The surest shield we have against future atrocities is our knowledge and our emotional understanding of what has happened in the past.”

The film will be screened at Holocaust Memorial Day events around the country in January, in line with the focus on survivors who have rebuilt their lives in the UK and their families.

HMD Trust chief executive Carly Whyborn said: “We are delighted that Daniel Radcliffe is once again lending his support to HMD.

“With this year’s theme, it is fitting that Daniel, who is so well known amongst younger audiences, has narrated our film.”

Among the survivors featured is Ben Helfgott, who was 10-years-old when the Nazis invaded his native Poland. Mr Helfgott went on to become an English weightlifting champion and represented Britain at the Olympics.
