For almost one hundred years there was only one way to make a movie — with film.

Movies were shot, edited and projected using photochemical film. But over the last two decades a digital process has emerged to challenge photochemical filmmaking.

SIDE BY SIDE, a new documentary produced by Keanu Reeves, takes an in-depth look at this revolution. Through interviews with directors, cinematographers, film students, producers, technologists, editors, and exhibitors, SIDE BY SIDE examines all aspects of filmmaking — from capture to edit, visual effects to color correction, distribution to archive. At this moment when digital and photochemical filmmaking coexist, SIDE BY SIDE explores what has been gained, what is lost, and what the future might bring.
