The Principle (2014): cast, story & where to watch

Released in 2014, The Principle is a documentary film directed by Katheryne Thomas, running about 90 minutes. “Are you significant?” — that tagline sets the tone.

What it’s about. "The Principle" brings to light astonishing new scientific observations challenging the Copernican Principle; the foundational assumption underlying the modern scientific world view. The idea that the Earth occupies no special or favored position in the cosmos has launched the last two scientific revolutions - the Copernican Revolution and Relativity - and, as Lawrence Krauss has said, we could be on the verge of a third, with "Copernicus coming back to haunt us". Interviews with leading cosmologists are interspersed with the views of dissidents and mavericks, bringing into sharp focus the challenges and implications not only for cosmology, but for our cultural and religious view of reality.

Who’s in it. The Principle stars Kate Mulgrew as Narrator, Michio Kaku as Himself, Lawrence Krauss as Himself and Charissa Saverio as Hologram, among others.

How it landed. With an audience score of 4.7/10, The Principle has proved divisive with audiences. It went on to earn $86.2K at the box office.
