Gone Girl actor Ben Affleck has helped launch a multi-media initiative from The ONE Campaign, founded by Bono, calling for a unified response to the Ebola epidemic in West Africa.

Affleck stars in a video alongside celebrities including Matt Damon, Morgan Freeman and Ellie Goulding, staring silently into a camera to illustrate that they're still waiting for world leaders to fight Ebola. The video has been released alongside the One Campaign's online Ebola Response Tracker, which shows how much money and resources countries have pledged to tackle the disease.
