Vox Pop Films is a documentary and commercial production company in Los Angeles. Founded in 2008, we specialize in documentary and non-fiction storytelling. As filmmakers for over 25 years, we thrive most when we’re creating work that has a lasting impact — whether that’s in politics, science, health or education.
Lisa Hepner
Lisa is a Canadian-American writer and documentary filmmaker. After graduating from Victoria College at the University of Toronto in 1993, she began her career as a journalist in Canada. Two years later, she turned her writing into producing non-fiction projects when she moved to New York City. From 1995 to 2011, she produced documentaries for the CBC, PBS, HBO, A&E and Sony Pictures Classics. Lisa learned much of her craft working alongside acclaimed directors, Michael Apted, Jonathan Demme, and Lisa F. Jackson, all of whom forgave her unfortunate lack of navigation skills.
In 2004, Lisa co-directed the documentary feature, Women on the Frontlines, that premiered at the United Nations and aired on PBS. Shot in Afghanistan, Burundi, Bosnia, Argentina and the U.S., it was her first foray into directing. Soon after, Lisa and her DP husband, Guy Mossman, started Vox Pop FIlms, a production company based in NYC. In 2009, they moved to LA where for the next 10 years, they focused on creating branded content and commercials while brainstorming ideas for longer films.
In 2022, Lisa directed her first documentary feature, The Human Trial with Guy. The film follows a radical stem cell treatment that might be the cure for diabetes. Since the film's release, it has been featured in the New York Times, NPR, The National News and Forbes, as well as the CBC and the Toronto Star. Now available on Prime Video, Apple TV and Documentary+, the film has been screened by more than 200 organizations, including Stanford University, the Tokyo Institute of Technology, Novo-Nordisk and on Canada’s Parliament Hill. The film was nominated for the prestigious Humanitas Prize in 2023.
Lisa is a member of the Producers Guild of America, New York Women in Film & Television, the Writers Guild of America, and Roco Voices, a speaker's platform for documentary filmmakers.
Guy Mossman
Guy is an American director and cinematographer who made his first short film in 2000 in Paraguay. In 2002, he was awarded a prestigious Park Fellowship at the University of North Carolina-Chapel Hill to pursue an M.A. in Journalism and Documentary Filmmaking. Since then, Guy has dedicated himself to lensing documentary films, non-fiction television and commercials. His love of character and vérité storytelling, and an eye for light and composition, has been acknowledged by critics and directors alike.
Guy is best known for his dramatic photography on the Oscar short-listed documentary film, Buck, which also won the Audience Award at Sundance Film Festival, Mariachi High, Bending The Arc, theSundance Film Festival Special Jury Award-winning Feels Good Man, and Discovery Doc’s The Lost Lincoln — EP’ed by Mark Wahlberg. He recently collaborated with David France on his HBO documentary, How To Survive a Pandemic, and with Dave Rivera on the Vice TV Original Series, Land of The Giants: Titans of Tech, based on the award-winning Vox Media podcast.
In 2022, Guy made his directorial debut with the acclaimed documentary The Human Trial, which he co-directed with his wife, Lisa Hepner.
His camera work on Buck was singled out in the Los Angeles Times for being ‘both beautiful and evocative’; and the LA Times TV critic Robert Lloyd said of Los Jets, ‘he gives every element its due; the clamor, the quiet, the details of décor and decoration, the richness of the landscape, the look of air under floodlights.’
Guy is a member of ICG IATSE 600.

Movie Review: ‘Buck’
