Peter Brown, veteran activist and the longest serving crew member ever aboard a Sea Shepherd Conservation Society vessel is releasing a new documentary film titled “Confessions of an Eco-Terrorist.” The film was created using hundreds of hours of footage, captured over the past three decades and provides a behind the scenes look at his high-seas activism exploits alongside Captain Paul Watson and the Sea Shepherd Conservation Society (think Whale Wars on steroids!).

The documentary highlights a number of successful campaigns that Peter Brown, Captain Paul Watson and crew have pulled off over the years and captures the dangerous and often illegal direct action efforts that led to the creation of the modern day Sea Shepherd Conservation Society.

In a recent video on Wired, Brown states that “The camera is the greatest weapon in the world; without the camera no one would know two guys stood in front of an icebreaker — there would be no environmental movement.”

“We’re called environmental terrorists, but are we the terrorists?” Brown asks. “My film answers that question.”

“Confessions of an Eco-Terrorist” premiered at the 64th Annual Cannes Film Festival 2011 and should be making its way into U.S. theaters by the end of the year.
