The arrival of cooler weather signals the start of a perennial favorite, the Port Jefferson Documentary Series.

Supported by the Greater Port Jefferson-Northern Brookhaven Arts Council and grants from the New York State Council on the Arts and the Suffolk County Film Commission, the PJDS begins its 22nd season on Monday, Sept. 21, at Theatre Three in Port Jefferson. The fall series, which will run through Oct. 27, marks the program’s 11th anniversary and the 22nd season of documentaries.

“We are very, very excited,” Lyn Boland, co-director of the film committee that has arranged the documentary series since 2005, said in a recent phone interview. Along with Boland, the committee — nicknamed the Film Ladies — includes co-director Barbara Sverd, Wendy Feinberg, Honey Katz, Phyllis Ross and Lorie Rothstein.

Seven award-winning documentaries will be featured this season, each complemented by a guest speaker who will answer questions at the end of the screening. This year’s selections will explore topics such as genocide, drug cartels, the online black market, art, tradition, cartoons and government cover-ups.

The process of choosing the documentaries is labor-intensive.“[The volunteer committee] gathers the movies from several different sources,” Boland explained. The members go to film festivals like the Hamptons International Film Festival and “try to personally grab one of the directors from one of those films. … We did that with ‘Meet the Patels,’ which was at the Hamptons last fall, and we showed it in the spring and it’s opening in theaters in September. So that’s like the dream sequence.”

Other festivals they regularly attend include the Tribeca Film Festival, the Stony Brook Film Festival and the American Film Institute’s festival in Washington, D.C. “So we try to go to festivals, we keep an eye on what’s going on in the news and we keep an eye long distance on the big festivals like Toronto, Sundance,” Boland added. “We also get a lot of emails from documentary organizations.”

The committee aims to screen films that people could not easily find elsewhere, so they avoid films that are streaming on services like Amazon or on television, for example.

When selecting the films, “We look for a great story that needs to be told,” Boland said. “We look for a film that’s well made because we really want to keep the standards up. We look for a subject that we haven’t shown too much of; something that’s new. We look for balance in the season. We also have to worry about our budget, being sure that we can afford the speaker and afford the distribution fee.”

Boland is most excited about the screening of the action-drama “Cartel Land.” She called the film — whose credits include executive producer Kathryn Bigelow, who directed “The Hurt Locker” and “Point Break”  — “an amazing story.”

“For a documentary to come out and be picked up by somebody who is as famous as she is and who is a feature director, it’s just an additional testament to how amazing this film is.”

The first five documentaries will be screened on Mondays at Theatre Three, 412 Main St., Port Jefferson, at 7 p.m. The last two will be screened at the Charles B. Wang Center on the Stony Brook University campus at 6 p.m., also on Mondays. Doors open one half-hour before showtime. Tickets for all films are $7 and will be sold at the door. Admission is free for undergraduate students at the Stony Brook screenings.

The group is always looking for volunteers of all ages to help out at the event.

“We want this to go on beyond us and it would be great to have enough volunteers to have a continuing staff that keeps renewing itself,” Boland said.
