Thanks for the info. Interestingly, I have seen very few indie films promoted through social media that reach me. I am on social media, I am a filmmaker, yet I receive almost no promotion of other people's films. Do you have an example?
One of the most prominent examples (although now classified as higher budget), would be A24, which always focuses heavily on social media marketing. On a much smaller scale, a recent project that received large notoriety is a short film called "nothing, except everything." - This film was created on a very limited budget by a high-school student; however, due to the quality and strength of the proof of concept and success on social media, the project received multiple offers and was picked up by TriStar Pictures.
Thank you for such a great thought on This mate, I have been bound in between creating without social media but I just realized that it plays a great role in building up your own audience as a filmmaker.
