Campaigners Speak Through Damon In New One Ad

The Bourne Identity star appears to be speaking direct to the camera in the new commercial - but his voice is provided by a series of unknown campaigners.

As Damon's lips move, women and men from several ethnic groups can be heard speaking through the actor.

The One ad thanks those who have donated to the cause so far, with Damon's voices explaining that millions of lives have been saved and "41 million more children have been able to go to school" and "three million more people living with AIDS have access to life-saving medication."

The campaign ad concludes with the plea, "In this election year, please join the millions of Americans from every party... who are coming together as one. We welcome your voice."
