WHO ARE WE at work when we’re not working? Experimental filmmaker Sharon Lockhart took years to find out, training her camera on the employees of Bath Iron Works in Maine as they rest their feet, open a book, stop for lunch, talk together or just enjoy the quiet in a corridor within the shipmaking plant. It’s a work of contemplative, humanist beauty that raises questions about the state — and the future — of American blue-collar labor. The Hirshhorn Museum screens the 80-minute Sundance favorite on Thursday.

The Grapes of Rock
Rocker Maynard James Keenan (Tool, A Perfect Circle) leads viewers down the rabbit hole of the fermented-grape juice industry in the movie “Blood Into Wine.” The documentary, screening after a wine tasting at Arlington’s Cinema ‘N’ Drafthouse on Thursday, follows Kennan and partner Eric Glomski’s attempt to wrestle a functional and well-regarded wine region out of northern Arizona’s dry earth. The two explore the craft, hang with their celebrity buddies and try to deflect the criticism, pessimism and mockery that come along with — well, heck, they’re trying to make wine in Arizona.

» Arlington Cinema ‘N’ Drafthouse, 2903 Columbia Pike, Arlington; Thu. April 22, doors open 6 p.m. for optional wine tasting before 7:30 p.m. screening; also at 9:50 p.m., $9; 703-486-2345.
