At Ptara, I directed two microbudget feature films. Make that nanobudget.
One had a crew of two (excluding the three actors, who also crewed, and a few kids who helped out on sound one day), and the other was basically me editing a large variety of footage to make it coherent. There were challenges in both, and everyone learned a lot. And, what these films lack in production values is made up for in performance and storyline.
By contrast, Tommy Wiseau’s “The Room” had a budget that was about 1000 times either of my films. He worked with a much more expensive kit and a more experienced cast and crew. Yet, “The Room” was filled with continuity errors, bad acting, and an incoherent plot.
