CAMDEN – The Camden International Film Festival opens Thursday, and will present 46 films that represent the best in documentary filmmaking. The festival runs through Oct. 3 throughout Camden, Rockport and Rockland.

The 46 films were selected from more than 300 submissions. Many are United States and regional premieres.

The festival, now in its sixth year, aims to present a snapshot of the cultural landscape through non-fiction storytelling, connecting filmmakers and industry representatives with audiences to discuss documentary film as an art form, a catalyst for change and as an outlet for the independent voice.

“This year’s Camden International Film Festival is our most ambitious program to date,” Benjamin Fowlie, founder and director of the festival, said in a news release. “We’ve got a number of international films making their first appearance in the U.S. along with several of this year’s most award-winning films from the festival circuit. The craft and quality of these stories are remarkable, and I’m extremely excited to share these incredible films with our audiences.”

Almost every film will be accompanied by a post-screening Q&A with directors or producers. The festival will also offer Points North Forum, which provides the New England filmmaking community an opportunity to connect with industry leaders and a number of funders, broadcasters and independent executive producers. About 50 industry representatives and filmmakers will attend.

Tickets are available online at www.camdenfilmfest.org. Pass options include the VIP Pass ($100) for admittance to all screenings, panels, special events and parties throughout the weekend; and the Festival Pass ($65) for admittance to all screenings and panels. Individual tickets ($8.50) also are available.

Among the films on the docket are “A Road Not Taken,” which tells the story of the solar panels that former President Carter installed on the White House roof. Ronald Reagan removed the panels — and dismantled Carter’s energy program.

All these years later, filmmakers tracked down the panels and traced their journey back from Maine to Washington, D.C.

“Do It Again” is about newspaper reporter Geoff Edgers’ quest to find the still-surviving members of The Kinks and convince them to reunite for his 40th birthday.

Venues include the Strand Theater, the Camden Opera House, the Bayview Street Cinema, the Rockport Opera House and the Farnsworth Art Museum.
