As city- and statewide lockdowns continue to prevent the spread of coronavirus, more and more celebrities are filming PSAs for American citizens (from the safety of their own homes, of course).

On Friday, the cast of HBO's Watchmendebuted "Washmen," featuring various actors, some in character, washing their hands for 20 seconds and urging viewers to do the same (but take it one step further than Laurie Blake and turn off the water, please).

Meanwhile, the Mailman School of Public Health at Columbia University virtually reunited the cast of Contagion, the 2011 pandemic movie currently surging in popularity, to do a series of PSAs about hand washing, social distancing, and more. (Experts from Mailman advised on the PSAs and consulted on Contagionduring production.) Participating actors included Matt Damon, Kate Winslet, Laurence Fishburne, and Jennifer Ehle.
