Brett Marty cut his teeth as a commercial director and made the transition to filmmaking with a handful of documentary projects. His narrative directorial debut, Youth, won a handful of jury awards and played at more than 30 festivals, including Cannes. His latest documentaries have been commissioned or featured by The New Yorker, The Atlantic and National Geographic. In previous lives, he studied ceramic sculpture at UC Berkeley, drove an old Buick from San Francisco to Argentina and helped Nate Silver launch Five Thirty Eight in 2008. He is the director of Save the Hearts (Mountainfilm 2019). In the film Eco-Hack! (Mountainfilm 2022), Marty and co-director Josh Izenberg wage a tech war against the overpopulation of ravens in hopes of saving the dramatically diminishing population of Mojave Desert tortoises. Eco-Hack! received a Mountainfilm Commitment Grant in 2020.
