The PSA with three Democrats and two Republicans is intended to break through the politics with a united, bipartisan message.
"This isn't over," Wilson says in the ad.
"So do your part," urges Schwarzenegger.
"Don't let COVID win, wear a mask," says Newsom.
The PSA is the kind of campaign U.S. presidents and former presidents would wage together in the past as a bipartisan, unified fight against natural disasters. For example, George H.W. Bush and Bill Clinton worked together on financial relief after the 2010 earthquake devastated in Haiti.
In different times, former living presidents like Barack Obama and George W. Bush would be called on by the sitting president to help with the kind of COVID-19 message represented here. But Trump has made a point of saying it's not his style to do such a thing.
In a written statement, Newsom, who has gradually allowed counties to reopen their economies said, "Simply put, we are seeing too many people with faces uncovered — putting at risk the real progress we have made in fighting the disease.
"California's strategy to restart the economy and get people back to work will only be successful if people act safely and follow health recommendations," Newsom said.
As of Sunday, there were more than 178,000 cases of COVID-19 in the state, with over 5,500 dead.
