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

Mostly, though, Pure Grain is Roberto Miller, writing and directing award winning films on streaming platforms such as Amazon, AppleTV, and Vimeo. The latest is The Four Lives of Federico Faggin, now released.

All told, Pure Grain makes films that connect the real world to the inner world. Our stories aim to inspire seekers to journey from fear to wonder. 

We are based in Mountain View, San Francisco, Portland, and Lyon, France.

A notable footnote: Roberto made the first all-digital film, the award-winning Mail Bonding, as featured  in American Cinematographer. He has also made commercials and videos for Silicon Valley companies such as Apple and HP, and studied creative writing at Stanford University while working for the Computer Science Dept. Earlier on still, he was a photo-journalist abroad, writing articles about music and sailing for The Wall Street Journal and Business Week, all after completing a far too sensible degree in computer science.


“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.”
