The cast of "Contagion," a 2011 film about a deadly illness that swept the world, has come together to offer a series of public service announcements advising the public about COVID-19, according to The Associated Press.

Movie stars Matt Damon, Kate Winslet, Laurence Fishburne and Jennifer Ehle worked in collaboration with Columbia University's Mailman School of Public Health to create four homemade videos with advice and messages of unity for everyone.

"A few years ago a bunch of us did this movie called 'Contagion' which we've noticed is creeping its way back up on the charts on iTunes for obvious reasons," Damon said in his PSA spot.

"Wash your hands like your life depends on it," Winslet says in her PSA video as she washes her hands. "Because right now, in particular, it just might."

In Ehle's spot, she emphasizes that the coronavirus is novel, underlining that nobody is immune to it.

"Every single one of us, regardless of age or ethnicity, is at risk of getting it," she says.

Meanwhile, Fishburne asks to help medical staff dealing with the coronavirus.

“If we can slow this thing down, it will give our doctors and our nurses in our hospitals a fighting chance to help us all get through this thing together,” he says.

The movie, directed by Steven Soderbergh, has experienced an uptick in popularity on film charts such as iTunes amid the coronavirus outbreak.
