Each week we’re recommending a movie from the film lover’s favorite home video company, Criterion. The Criterion Collection is dedicated to gathering the greatest films from around the world and publishing them in editions of the highest technical quality with supplemental features that enhance the appreciation of the art of film. This week, A Brief History of Time.

Errol Morris turns his camera on one of the most fascinating men in the world: the pioneering astrophysicist Stephen Hawking, afflicted by a debilitating motor neuron disease that has left him without a voice or the use of his limbs. An adroitly crafted tale of personal adversity, professional triumph, and cosmological inquiry, Morris’s documentary examines the way the collapse of Hawking’s body has been accompanied by the untrammeled broadening of his imagination.

Telling the man’s incredible story through the voices of his colleagues and loved ones, while making dynamically accessible some of the theories in Hawking’s best-selling book of the same name, A Brief History of Time is at once as small as a single life and as big as the ever-expanding universe.
