But not every filmmaker is happy with the digital revolution that has swept the industry - including some major practitioners of the craft.

Produced and presented by movie star Keanu Reeves, new documentary Side by Side sees top names in the film world discuss the pros and cons of digital filmmaking.

Talking Movies' Tom Brook reports.
