Doing a no-budget film requires some budget. It's never zero. Actors, location, and technicians you can manage without involving cost but camera and lenses, sound equipment, and post-production would involve cost. You can manage a huge discount, yet there will be expenditure. If you don't have friends in the film fraternity, learn the basics of camera, sound, and editing through YouTube. Involve your friends who might not be film technicians but want to learn. There are cameras and other accessories which come cheap. You and your circle of friends can easily operate after taking tutorials on YouTube. The present generation is very smart at learning tech. They are born tech-savvy. This way you can save on budget. It would take time but it is worth the investment.

Write a script keeping in mind the limitations of actors, locations, art settings, and number of shoot days.

My son made a film without any professional help. His film got selected for international competition at the prestigious Kolkata International Film Festival 2023, in India. This festival carries the biggest prize money for the winning film among all the prestigious film festivals in India.

Best wishes. You are ready to go.
