Let’s all take a moment to remember the $22k film that would become the $240M grossing Blair Witch Project.
In 1999, The Blair Witch Project was in the Guinness Book of World Records for “Top Budget to Box Office Ratio” for a mainstream feature film. The film cost $22,000 to make and grossed $240.5 million, a ratio of $1 spent for every $10,931 made.
In my book it is one of the first successes in transmedia storytelling, receiving acclaim both critically and commercially, and giving rise to the ultra-realistic style of horror films that is popular today. (Paranormal Activity, anyone?)
