Heard from a Tamil movie maker (Arun Bose) about how to make zero budget (well, almost zero budget) at The Goa Project. Arun made a one minute clip to start his movie making journey. Emboldened he made a 30 minute movie (frugally) during his student days and now he has embarked on a full length feature.
He starts with a framework (a powerful one). The crew takes a bus to the location and modifies the script based on what is available in the location. Once they know what is to be shot, the actors arrive the next day. And everyone organically evolve the movie. The movie is 'Alaiyin Thisai' - check it out.
I see that there will be many more adventure seekers like us in the future.
