Artist, activist and filmmaker Ai Weiwei's epic and poignant look into the global refugee crisis, brought on by famine, war and climate change.

Over 65 million people around the world have been forced from their homes to escape famine, climate change and war in the greatest human displacement since World War II.

Human Flow, an epic film journey led by the internationally renowned artist Ai Weiwei, gives a powerful visual expression to this massive human migration. The documentary elucidates both the staggering scale of the refugee crisis and its profoundly personal human impact.

There will be a post-screening Q&A via live Satellite feed of Ai Weiwei in conversation with Jon Snow and Special Guests.
