CIFF Selects and Unity College will present a free screening of the documentary film “A Fierce Green Fire: The Battle for a Living Planet” Wednesday evening, Sept. 4, at the Unity College Center for Performing Arts, 42 Depot St. The screening will start at 7 p.m. and will be followed by a Q&A led by Camden International Film Festival Founder and Executive Director Ben Fowlie.

“A Fierce Green Fire” is the first big-picture exploration of the environmental movement’s grassroots and global activism, spanning 50 years from conservation to climate change. Directed and written by Mark Kitchell, Academy Award-nominated director of “Berkeley in the Sixties”; and narrated by Robert Redford, Ashley Judd, Van Jones, Isabel Allende and Meryl Streep, the film premiered at Sundance Film Festival 2012, has won acclaim at festivals around the world and in 2013 begins theatrical release, as well as educational distribution and use by environmental groups and grassroots activists.

Inspired by the book of the same name by Philip Shabecoff and informed by advisors like Edward O. Wilson, “A Fierce Green Fire” chronicles the largest movement of the 20th century and one of the keys to the 21st. It focuses on activism, people fighting to save their homes, their lives, the future — and succeeding against all odds.

CIFF Selects is an outreach program of the Camden International Film Festival. CIFF is recognized as one of the top 25 film festivals in the world for documentary films and filmmakers; for more information, visit camdenfilmfest.org. The 2013 festival runs Sept. 26 through 29.
