The cast of HBO's Watchmen has launched a public service announcement encouraging fans and viewers to practice proper hygiene in the wake of the coronavirus (COVID-19) pandemic.Watchmen writer/story editor Jeff Jensen posted a video of the PSA on Twitter, appropriately titled "Washmen."

The "Washmen" video features Regina King (Angela Abar/Sister Night), Tim Blake Nelson (Looking Glass/Wade Tillman), Jean Smart (Laurie Blake/Silk Spectre), Yahya Abdul-Mateen II (Cal Abar/Jon Osterman/Doctor Manhattan), Tom Mison (Mr. Phillips), Sara Vickers (Ms. Crookshanks), Dustin Ingram (Agent Petey), Jovan Adepo (Will Reeves/Hooded Justice) and Andrew Howard (Red Scare). In it, each of the actors give various tips on how to wash your hands, all while staying in character.

Perhaps the most hilarious and informative parts of the video came from Smart, Ingram and Mison. Smart, while washing her hands, flung several insults toward her former paramour Doctor Manhattan; Ingram was dressed in a Sister Night costume, complete with eye makeup; and Mison gave a spot-on impression of Jeremy Irons, who portrayed Adrian Veidt/Ozymandias in the series.
