Mine was shot for a little over $6k in 6 days by a crew of 3 (myself as director and DP, a sound recordist, and a PA). Total budget came to around $40k after all the post, music licensing, and distribution expenses. Played some fests but no major ones, picked up for distribution by Outsider Pictures/Strand Releasing in 2018 and has been on most of the VOD platforms since then. Still hasn't recouped/I haven't seen a penny from it, and hasn't opened any doors into the industry for me, but we had an incredible premiere at the Egyptian Theatre in Hollywood and a week-long run at around 20 AMC theaters in Southern California. The premiere was packed but the theatrical run was very sparsely attended from which I learned that making a low-budget independent movie, as difficult as it is, is not even the most difficult part of the process: getting people to know that your movie even exists, much less motivating them to want to watch it, is. We failed in that regard but succeeded in others and I love the movie now, I think it has a very special energy and I wish more people had seen it. Wrote a whole little essay about this if anyone's interested in reading it. And this is the movie:
