Sarah Clarke is an award-winning TV and film actress (Bosch, 24, Twilight) whose lifelong passion for wildlife preservation and environmental protection led her to Thunderheart Films. A founding member of the company, Sarah has spent the last year producing and developing three of our projects - Iniskim, Buffalo Resurrection, and an unannounced film.


Throughout her career onscreen she has supported and worked with various environmental agencies including the NRDC, Earthjustice and Arts Earth Partnership and her Thunderheart work has become an extension of that passion.

Daniel Glick has directed and produced a wide range of narrative and documentary shorts, commercials, web series and more. His first feature documentary film, A Place to Stand (2016), the true story of poet Jimmy Santiago Baca, has been called “inspiring” (Booklist), “gutsy” (Library Journal) and “compelling” (Santa Fe New Mexican).

In 2016, he completed Our Last Refuge which tells the story of the Badger-Two Medicine, the sacred homeland of the Blackfeet, and the 35-year struggle to protect it from oil and gas exploration. It was this film that led him to connect with the Blackfeet Buffalo Program.
