How I Shot a 140-Page Script in 10 Days — Completely Solo

The full rig. 6–7 kg strapped to my body for 10 straight days of shooting.

I’m Buzz — a one-man filmmaker based in Japan. I write, direct, shoot, light, record sound, edit, cast, and market everything myself.

This time, I took on the biggest project of my career: a mystery drama that starts as a 3-episode YouTube series and concludes with a live stage performance featuring piano accompaniment. The title is “KAIMAKU TEN MILLION” (Opening Night: Ten Million). This is the production diary.

Pre-Production

February 2026. I start writing. The original plan is a short drama plus a stage reading — small scale, manageable solo.

The script keeps growing. By early March it’s 120 pages. Feature-length. The story is getting better, so I refuse to scale down. (I will deeply regret this decision.)

March is consumed by casting. Once I start being picky, I can’t stop. The main cast isn’t locked until early April. Meanwhile the script keeps expanding — final draft lands at 140 pages.

Building the Schedule

Coordinating availability for a large cast, securing locations, and figuring out how to break 140 pages into shootable blocks — all of this has to fit into a single scheduling document called a “koban” (the Japanese equivalent of a stripboard).

I settle on 10 shooting days. The story is an ensemble drama with constant scene intercuts, so building the schedule feels like solving a jigsaw puzzle.

Then there’s the costume schedule. With this many actors and this many crosscuts between timelines, tracking who wears what in which scene is a nightmare. Doing it solo is honestly beyond my capacity.

Final Sprint Before Day 1

Two weeks between the read-through and Day 1. I’m rewriting scenes based on the cast’s feedback while simultaneously booking locations, coordinating with the city for PR, and confirming schedules with talent agencies.

Normally I draw storyboards before shooting. This time there’s no time for that.

Blackmagic Design kindly lends me a PYXIS 6K for this project. The night before Day 1, I mount it on the RONIN RS5 and run camera tests until 3 AM. I go to set having barely slept.

10 Days of Hell

The real hell starts once the camera rolls. I’m fighting a brand-new camera system while directing a feature-length ensemble cast. Every day demands 100% of my physical and mental capacity.

Wrap doesn’t mean the day is over. Back home, I build the next day’s final schedule, send updates to every agency, check all the gear, back up the footage. Sleep is almost nonexistent. The next morning I load the car and drive to set again.

Dehydration

PYXIS 6K, RONIN RS5, and a DIGITALFOTO THANOS gimbal support vest. 6–7 kg of camera rig on my body at all times while I shoot and direct simultaneously.

Break time isn’t rest. It’s swapping lavalier mics, charging wireless units, ordering lunch, adjusting lights. There is no actual downtime.

I’m sweating constantly under the heavy rig but barely drinking water. I notice something is wrong in the bathroom. A cast member tells me my eyes are turning yellow. Back home, the nausea is so bad I can’t sleep.

At 2 AM I run to a convenience store and chug OS-1 (an oral rehydration drink). It tastes sweet and delicious. Apparently, when it tastes good, you’re in serious trouble.

The Final Days

Every day I’m on the verge of collapse. But the cast is genuinely wonderful, and the energy on set keeps me going.

No matter how brutal things get, the moment I capture a beautiful shot, the exhaustion vanishes. That’s what I do this for.

Ten days of shooting, complete. No thrown-out back. No hospital visit. I’ll take it.

About the Project

“KAIMAKU TEN MILLION” (Opening Night: Ten Million) is a hybrid YouTube drama + live stage production — a mystery revolving around ¥5,000,000 that vanishes from a safe.

The drama is a 3-episode series (approx. 40 min each), streaming from late May 2026. The stage performance takes place June 25–26, 2026, at J:COM Urayasu Concert Hall, featuring live piano accompaniment.

Synopsis

Kyo, a 19-year-old aspiring director, organizes an independent stage production of Kenji Miyazawa’s “Night on the Galactic Railroad” to launch his childhood friend Maria’s acting career. The cast he assembles is a group of broken people — a disgraced actress, a pianist who lost her career in an accident, a voice actress being blackmailed by the underworld.

Then ¥5,000,000 disappears from a safe. All six cast members are suspects. A detective storms into the rehearsal space and begins interrogating them one by one. When all the interrogations are over, the curtain rises on “Night on the Galactic Railroad.”
