People watching Hollywood awards ceremonies on television often see stars walk the red carpet in costly clothing. But the worldwide coronavirus has changed even Hollywood, America’s movie production center in California. Red carpets of the future might be very different, if the custom happens at all. Photographers and fans stand along the red carpets, while celebrities stop to have their picture taken. It is a usual part of publicity efforts that come with a new film opening. But, social distancing may put a stop to it. “Everybody is desperate to get back to a normal version, where we get to be with people in person,” said one Hollywood publicist who asked not to be identified. “I don’t see it coming back fully until we’ve got some kind of vaccine,” the publicist said.
