Pure Grain is a swell film company. It swells between one and forty people depending on the production.

Mostly, though, Pure Grain is Roberto Miller, writing and directing award winning films such as Mandorla, now available on AppleTV, Amazon, Vimeo, Google Play, and Gaia

All told, Pure Grain makes films that entertain a connection between the real world and the non-physical world, and in the process, aspires to spark a conscious shift from fear to empathy and wonder. 

We are based in San Francisco and Lyon, France.

Projects in 2020 pipeline:

  • From Computers to Consciousness, post-production
  • The Four Lives of Federico Faggin, post-production
  • Ascension, in development

A notable footnote: Roberto made the first all-digital film, the award-winning Mail Bonding, as   featured  in American Cinematographer.


“Thank you for sharing such a treasure of beauty and authenticity. It is pure, guided, gently disruptive and full of magic. Thank you for inviting us on a journey into ourselves.”

“”The film really touched me because of its theme—a change of life, a more real life, more attuned to what we want to live—a theme very familiar to me.”

“I have not found myself as spellbound from a movie in quite a few years. “Mandorla” kept my interest riveted until the very end. Am looking forward to Roberto Miller’s next cinematic effort.”

“I really loved the music, the camera work, the natural light and the actors’ performances. I also loved the atmosphere of ambiguity, uncertainty even confusion, the “anti-hero” quality of the main caracter, the fact that it triggers a process of questioning in the viewer’s mind, with no “pat” or “easy” answer.”
