The short is called Jackals & Fireflies and appears to center on a woman going through some sort of life change.

There have been quite a few films shot on phones. However, in most cases, an iPhone is the cinematographer’s tool of choice for shooting.
It looks like Academy Award-winning screenwriter and acclaimed director Charlie Kaufman wants to buck that trend, though. Today, a trailer dropped for a short film directed by Kaufman, and it was shot using only a Samsung Galaxy S22 Ultra. You can see the trailer above or check it out on YouTube.
