Celebrity A-listers have joined the One Campaign in a chilling PSA to help gain support and fight against the Ebola crisis in West Africa.

Ben Affleck and Matt Damon are just two of the many big names to join the campaign, which was co-founded by U2’s Bono with the goal of taking action to end extreme poverty and preventable disease, particularly in Africa.

The video features celebrities staring blankly into the camera as the viewer waits for something to happen–though it never does. The silence results in a powerful message that waiting to take action only results in more deaths and devastation.

Other celebs involved include: Will Ferrel, Ellie Goulding, Connie Britton, Akon, Thandie Newton and Morgan Freeman.  Two Liberian health care workers and two African musicians also appear in the short video.

Along with the PSA comes a petition to urge leaders to take action. It reads:

The world waited too long to respond to Ebola. Ebola is devastating West Africa. And every day we continue to wait – for funding to reach the ground, for nurses and doctors to be deployed, for the shattered medical services to be rebuilt – more people die.

Leaders from every nation—not just the usual suspects—need to stop waiting and act.

According to the World Health Organization, nearly 5,000 people have died from Ebola in Africa.  There have been four cases in the United state, one of which has resulted in death.
