Matthew McConaughey has wowed us with various roles throughout his decades-spanning career, but the actor’s latest character has the potential to save lives.

The Oscar winner posted a video to social media of him as "Bobby Bandito," a new persona he has taken on to teach fans how to make their very own face masks using a few household items we likely already have: a bandanna, two rubber bands and a coffee filter.

"I say it's high time to catch this killer, 'cause we got more living' to do," he said in the minute-long video after nailing a wanted poster for COVID-19 to a tree.

"Now remember, stay at home. But if you gotta go, strap it on like so," he added, urging everyone to work together to defeat the coronavirus "Bobby B-style."

In addition to filming PSAs like this, McConaughey and wife Camila Alves recently joined forces with Bethenny Frankel to donate protective masks to essential workers -- like those in health care as well as police officers and firefighters -- amid the pandemic.

"#BStrong is so grateful to @camilamcconaughey and @officiallymcconaughey for getting involved in this fight and donating funds for 80,000 protective masks to be distributed to the warriors on the front lines of this pandemic who are risking their lives to save ours," the businesswoman and former "Real Housewives of New York City" star wrote Friday.
