Green Day is stepping off the stage and onto the big screen. The punk rock trio just dropped the trailer for “Nimrods,” a comedy hitting theaters August 14th.

Details are still thin, but the film features a fictional band called the Analog Dogs opening for Green Day. The band hasn’t clarified whether they’re starring in the movie or if it’s inspired by their decades on the road.

The title nods to “Nimrod,” Green Day’s 1997 album that gave us “Good Riddance (Time of Your Life)” and showed the band could do more than three-chord ragers. Whether the film connects to that era or just borrows the name remains to be seen.

In other Green Day news, the band launched “Idiot Nation” on SiriusXM Channel 314, a station playing their influences, peers from the East Bay punk scene, and deep cuts from their own catalog.

This isn’t Green Day’s first screen rodeo. They’ve dabbled in documentaries and the “American Idiot” stage musical. But a straight comedy? That’s new territory for Billie Joe Armstrong and company. For a band that’s never taken themselves too seriously, it tracks.
