For its new "Academy Originals" video series, The Academy of Motion Pictures Arts and Sciences created a documentary short called "'Not Much To See': How the Blind Enjoy Movies" that explores how the visually impaired "watch" movies without seeing a thing.
For the short, three notable blind people were interviewed: Blind Film Critic's Tommy Edison, Blind Girl Blog's Melissa Hudson, and Mario Garcia, winner of the 2013 Braille Institute "Cinema Without Sight" award.
Good storytelling and descriptive audio is important, but what really assists them is a free narration service called Audio Description. In selected theaters, moviegoers can put on a pair of special headphones and get clued in on what sighted folks take for granted.
Remember the scene from "Raiders of the Lost Ark" where a giant stone ball is about to crush Indiana Jones? Wait until you HEAR it described with zero visuals in this mini-doc. Very cool.
