In collaboration with the UN's refugee agency, UNHCR, Cate Blanchett, Peter Capaldi and Kit Harrington along with an array of other Hollywood stars have made an impassioned and poetic plea for the plight of the world's refugees,

Reading the rhythmic poem "What they took with them" by Jenifer Toksvig the actors relay the pain and uncertainty of refugees fleeing their homes. The stars, including Keira Knightley, Stanley Tucci, Chiwetel Ejiofor and Jesse Eisenberg read a list of possessions carried by refugees based on real life testimony.

Starting with practical possessions such as plastic rugs and pillows the lines of the poem move to the more personal; jewellery, and sacred texts to finally the intangible. "With my soul, with my smile with my life," the poem ends.

The video, shared exclusively on Facebook features the photographs of Brian Sokol from his project "The Most Important Thing".

The footage opens on a helicopter flying over Syria, a trail of barrel bombs falling in its wake. The video asks "If you had to flee your home what would you take?" as the bombs explode and stricken survivors covered in dust run from the blast site.

The video closes quoting recent UN statistics which show more than 65 million people around the world are currently living as refugees." Across the world 65 million people have been forced to flee their homes. We stand with refugees," the text reads.

The number of refugees has doubled over the past decade, the worst displacement crisis the world has faced since the end of the Second World War. The shocking figures have been fuelled by protracted conflicts in Afghanistan and Syria. Has ssaid half of those displaced globally have come from those countries.

The world's largest refugee population has been forced to leave Syria. The majority have been externally displaced to Lebanon, Turkey and Jordan.

The video is part of the UN's WithRefugees campaign which aims to shine a spotlight on the plight of refugees ahead of the UN General Assembly on 19 September.
