Elstree 1976 is a Kickstarter-funded documentary about Star Wars extras. From the documentary's Kickstarter site:
In 1976, during the hottest summer on record, Star Wars was shot in suburban North London. Nobody involved had any idea how big the film would become, many couldn't even remember the title.
Yet, for the extras and actors in smaller roles, their faces hidden in masks and helmets, this seemingly insignificant job would go on to colour their lives even four decades later.
ELSTREE 1976 is a portrait of a cross-section of these people; from the man inside the most iconic villain in film history to the guy whose character was completely cut from the final film. It tells the stories of their lives and explores the eccentric community they have formed, traveling the world, signing autographs for fans.
The trailer is very good. Please consider backing this project. The filmmakers are looking for £30,000 (US$50,000) and are £7,000 of the way there.
