ROCKLAND — “Truth Tellers,” a new documentary feature directed by veteran Maine filmmaker Richard Kane, has its world premiere at the Camden International Film Festival (CIFF) Sept. 16 through 27 virtually. A special, in-person screening with the filmmaker and subject Robert Shetterly takes place at the Strand Theatre, 345 Main St., Sunday, Sept. 19, at 1 p.m. After the screening, there will be a live Talk Back with director Richard Kane, subject Robert Shetterly, Maine legislator Rachel Talbot Ross, and a special guest from the film. Tickets are available at pointsnorthinstitute.org/films.

The film premiere is being launched simultaneously with Shetterly’s latest book, “Portraits of Racial Justice: Americans Who Tell the Truth.” Following the premiere, Shetterly will sign books at a reception at Caldbeck Gallery, 12 Elm St.

Artist and activist Shetterly has painted 255 portraits of Americans, past and present, who had the moral courage to confront issues of social, environmental and economic justice. These “Americans Who Tell the Truth” have been exhibited throughout the United States for almost two decades. “Truth Tellers” is both a story of Shetterly’s art and activism and a history lesson in what it means to be a citizen of a democracy. In bringing Shetterly’s message to a wide audience, “Truth Tellers” will spark a national conversation on truth telling.

Among the truth tellers in the film are Bayard Rustin, Bill McKibben, Kelsey Juliana, Rev. Lennox Yearwood, Sherri Mitchell, Maulian Dana, Bill Bigelow, Zyahna Bryant, Bree Newsome Bass, Fannie Lou Hammer, John Lewis, Rev. Martin Luther King Jr., Reggie Harris, and others.
