(2019)  The thrilling inside story of NATIONAL GEOGRAPHIC's top "Scientific Discovery of the Decade," the discovery of gravitational waves from deep space, 2015-1017, which opened up the 95% of the universe that has been dark to our existing observatories and space telescopes.  It's the violent "warped side" of the universe described by Einstein -- colliding black holes and crashing neutron stars -- never seen before LIGO detected this remnant and messenger from the first observed cataclysmic collision of two black holes.

Guthman witnessed and filmed this dramatic and emotional peak in the lives of the 1,000 rebel scientists around the world who risked their careers on a 50-year, $1 billion search. The discovery earned the film's three principal characters, Kip Thorne, Rai Weiss and Barry Barish, an immediate 2017 Nobel Prize in Physics, an enchanting week in Stockholm that became the documentary's finale.

"LIGO" begins innocently as Guthman and his crew arrive at the LIGO Livingston Observatory outside Baton Rouge in September 2015.  Then almost immediately they are swept up in one of the great human experiences in recent history, scientific or otherwise, lasting and filmed over two years.  And one that revolutionized our understanding of the universe.

(2018)  An epic journey through the ocean kingdom of the Atlantic Salmon, in an attempt to unravel the mystery of their imperiled life at sea.  Salmon are plummeting to critical levels, verging on extinction in the wild.  The cause is mortality at sea.  For the 1st time, using the latest DNA technology, scientists are tracking the salmon from the European and Canadian rivers into the vast North Atlantic and back again, in hopes of finding an answer before it's too late.  Directed by Deirdre Brennan.  Narrated by Gabriel Byrne.

"Messner's solo climb of Everest is a deed widely regarded as the greatest mountaineering feat of all time."

From the Hudson River in New York to Santa Monica Bay in Los Angeles, from the Neuse River in North Carolina to the Cook Inlet in Alaska, the Willamette River and Puget Sound in the Pacific Northwest, "The Waterkeepers" gives a dramatic chronicle of the 40-year battle to clean up America's rivers, bays and oceans. .

In 2010, Guthman edited The Waterkeepers and The Hudson Riverkeepers (below) into one feature documentary, which premiered at the DC Environmental Film Festival on the 10th and 12th anniversaries of The Waterkeepers and The Hudson Riverkeepers showings at the festival.

(2010)  Skiing Everest is the first documentary about the small elite fraternity of high-altitude skiers who climb the highest peaks in the world in pure Alpine style, carrying their skis and declining to use supplemental oxygen. At the top of the world, high in the Death Zone, they lock into their skis and challenge the most dangerous slopes in the world - under weather conditions that are as perilous as the thin air, hidden crevasses, and 10,000 ft. sheer faces that drop into Nepal and Tibet far below.

"This film will make you hold hour breath again and again.  Skiing Everest is something most of us, mere mortals, will never get to do, and yet, the Marolts figured out how to take us with them.  What a gift!”

-- Robert Redford

Filmed around the world, it features skiers Mike Marolt, who was also director of photography, Steve Marolt, Hans Kammerlander, Chris Davenport, Laura Bokas, Mark Newcomb and the late Fredrik Ericsson (who died the following year skiing on K2).   Skiing Everest was licensed by ESPN in 2011 for broadcast in the United States and Europe.  It was converted to 3D in 2012.  

"There’s no denying the beauty of the locales the brothers visit on their far-flung expeditions, and when combined with snappy editing and very capable technical specs, pic is a very vivid and high-caliber travelogue.”

(2006)  Churning the Sea of Time: A Journey Up the Mekong to Angkorpremiered at Lincoln Center in April 2006.  It was an official selection of the Museum of Modern Art's "Directors Fortnight Expanded" in 2007 and was shown at the Royal Geographical Society in London, the Smithsonian in Washington, DC; and the Asia Society in New York, among other featured screenings.

One of the most mythic and potent journeys of our time, up the Mekong River through the exquisite, complicated terrain of Vietnam and Cambodia to the great ruins at Angkor - the magnificent Khmer temples built from the 9th-13th centuries AD that are being painstakingly restored deep in the Cambodian jungle.  Director Les Guthman travels by boat up a river whose raw beauty and power were celebrated by Marguerite Duras in the 1920s.  But in our time it became known as "the river of evil memory" as it coursed through Southeast Asia in the second half of the 20th century.  Today, the river in Vietnam is filled with the vibrant life of a young nation free of a century of war.  In Cambodia the past weighs far heavier.  We travel up the Mekong passed Phnom Penh, once called "the beguiling beauty of SE Asia," toward the Laotian border in search of the almost-extinct fresh water dolphins of the Mekong; then return back to the capital and head northwest up one of the world's unique natural wonders, the Tonle Sap River, and across the great Tonle Sap Lake, one of the planet's most abundant fisheries.  In Angkor, World Monuments Fund experts describe their 15-year restoration of one of the jewels of a city called "the eighth wonder of the world."  And as they take us on an insider's tour of Angkor, we learn that the story of their work there is not only a story of the rebirth of Angkor after the horrors of the Khmer Rouge Era, but it is also a story of the rebirth of Cambodia.  A stunningly filmed odyssey up a river far distanced in time from the corridor into the heart of darkness portrayed in Francis Coppola's "Apocalypse Now."

(1996)  Norman Corwin was the legendary writer, producer and director during the Golden Age of Radio.  CORWIN was licensed by WNET in New York and aired on PBS.  KCET in Los Angeles picked up the license in 1999. Actor Charles Laughton, in the early 1940s, is quoted in the film as saying, "There is no actor in Hollywood or on Broadway, who would not drop what he is doing to be in one of Norman Corwin's radio plays. We all look up to him as a writer of the highest caliber and one of the most important writers in America today." 

The Hollywood Reporter in its review of CORWIN wrote, 'When you peruse the cultural landscape, there are not that many folks who have achieved the acclamation of national treasure.'

(2000)  For more than two decades, environmentalists have come to Belize to try out new strategies to protect its pristine rain forests and rich biodiversity from the same economic threats - poverty and rampant economic exploitation - that continue to ravage so much of the Amazon Basin in Brazil and Peru. In this pioneering film, journey deep into this fragile paradise to look at two of the most ambitious - and most endangered - of these cutting-edge experiments: a multi-village cooperative to create a vast Howler Monkey preserve with the goal of protecting its habitat, while providing a thriving Eco-tourism economy; and a manatee sanctuary on the Belizian coast to protect the manatee and the critically endangered Hawksbill turtle, where it was human nature that became the greatest and most unexpected threat.   We also go on a magical trek by horseback through the magnificent Slate Creek rainforest preserve on Belize's rugged border with Guatemala. All three projects are models for how fragile ecosystems can be protected anywhere in the world, while enriching the lives of the local people.   Narrated by NPR's Warren Olney.
