If you loved Jam Films, try Egg
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Yukihiko Tsutsumi, and they both carry the 3am cult mood tag, and they sit in Comedy / Drama / Fantasy territory. If that's the register that drew you to Jam Films, the second film will land in a comparable space — through a different lens.
3am cult
What Egg is
Morning train ride, fluorescent hum. Between blinks a golf-ball-size egg appears. Hatch and glare—each eyelid snap births something worse. Egg.
