I Put Myself in 6 Movie Fight Scenes With AI. Here's What Broke.

Free kit: the pipeline, the real prompts, a continuity lock sheet and the FFmpeg commands I used to check every clip are in the AI Fight Scene Continuity Kit. No sign-up.

Every AI video demo looks perfect. One clean shot, a cool caption, done.

What you don't see is the twenty takes where the sword disappeared, the bad guy's face changed, or the lightsaber bent like a pool noodle.

So I put myself in six movie fight scenes. This post covers the finished scenes and, more usefully, the stuff that broke on the way there.

Before we start

• This is a build-in-public demonstration, not a step-by-step tutorial. The step-by-step lives in the free kit.
• Built in October 2026. Models, prices and content filters change, sometimes week to week.
• Every face in these scenes is mine. The voiceover in the video is my cloned voice.

The setup

I gave Claude Code two reference photos of me, a headshot and a full-body shot, and had it drive Higgsfield:

1. Nano Banana makes the still keyframes, about seven per scene.
2. Kling and Seedance turn each keyframe into a short video clip.
3. Short bridge clips connect every shot, starting on the last frame of one and ending on the first frame of the next, so it plays like one camera instead of a slideshow.
4. Everything gets checked frame by frame before it goes in.

That last step is the part nobody shows you. It's also the part that matters.

For scale: the six scenes took about 690 generation requests, 256 stills and 433 video clips, counting every retry. Most of those weren't first drafts. They were fixes.

Star Wars: the bent lightsaber

I'm a grey Jedi fighting stormtroopers in a ruined temple. The first version looked cool for about five seconds. Then my robe changed color between shots, the lighting jumped from sunset to midnight, and in one shot my lightsaber bent into a thick, warped club.

So I rebuilt it. Three things fixed it:

• One locked costume image passed as a reference on every shot. The robe stopped changing.
• The same lighting sentence in every prompt, word for word.
• Describing the blade's shape and banning the move that broke it: "a single rigid straight thin crimson red blade like a solid rod of light that never bends", "small, tight, controlled movements", "never spins and never turns his back".

It turns out spins are what break the blade. The more a character rotates, the more the model has to reinvent what's in their hands.

Game of Thrones: the ending matters

Beyond the Wall, fighting White Walkers. This one taught me that the end of a scene matters as much as the start. The old version had ten seconds of the back of my head, two random ice monsters that showed up and never did anything, and the Wall appearing out of nowhere.

The fix wasn't more footage. It was less. I cut the junk and ended on one strong shot: the sword planted in the snow, and a prompt that spells out what must not appear ("no glowing eyes, no new creatures, nothing appears in the trees").

Naruto: the details only a fan catches

Sage mode, shadow clones, Rasengan. This is where small details almost wrecked it:

• The hand signs for the fire jutsu were wrong.
• The fireball lit, stopped, and lit again.
• The enemy at the end was wearing a Leaf headband, which is my own village. That's not a small mistake if you actually watch the show.

None of those are things an AI catches on its own. You catch them because you care about the thing you're making.

Dragon Ball Z: keep it looking like me

The hardest one to keep looking like me. Once I went Super Saiyan, the model kept trying to turn my face into somebody else. It also kept putting a symbol on the back of my gi that I never asked for.

The lesson: decide what has to stay fixed, then check it in every single shot. Not most shots. Every shot.

Ninja Turtles: stop asking for what it's bad at

A ninja in a red bandana fighting the Foot Clan. I originally switched between a katana and twin sai. The sai shots were buggy, so I cut them. The katana alone was cleaner.

Sometimes the best fix is to stop asking the tool for the thing it's bad at.

Yakuza: the lapel and the boss

Closest to real life: dark suit, white shirt, how I actually dress, fighting yakuza in a neon city. Two fixes.

First, the jacket came out with notch lapels. I wear peak lapels. Nobody else would have noticed. I would have, every time I watched it. So the whole scene got rebuilt with "sharp PEAK LAPELS" in every prompt.

Second, the boss I fight one on one was bald and heavy in one shot, then a completely different guy in the next. Your face is locked by your reference photos. Nobody else's is. I cropped the right boss out of a good frame and passed it as a reference too.

What AI actually changed

It didn't replace taste. It replaced the camera crew, the set and the budget.

Here's what still took a human: noticing the boss changed faces. Knowing the hand signs were wrong. Knowing a Leaf ninja shouldn't be the villain. Deciding a scene was done.

The tools generate. You decide what's good enough to keep.

Who should try this, and who should skip it

Try it if you want cinematic B-roll, a thumbnail, or a concept trailer for an idea you can't afford to shoot yet.

Skip it if you want one prompt and a finished movie. You'll be frustrated. Every scene here took multiple rounds of fixes. And the content filters change: prompts with franchise names that worked one week got blocked the next. Describing what's on screen ("glowing crimson red energy sword", "soldiers in glossy white segmented armor") worked better than naming it.

The line I won't cross

I used my own face for this. That's the line for me. Putting yourself in a scene is fun. Putting someone else's face in a fight scene without their permission is not the same thing.

And if you post something like this, be upfront that it's AI. Don't let people think you flew to Tokyo and fought the yakuza. On YouTube, that means answering yes to the altered or synthetic content question.

Fan scenes built on famous franchises are also a gray area. I'm not selling these or using them in ads. Ownership can be complicated, so don't assume generating something gives you unlimited rights to it.

Your next move

Try one scene this week. One shot of you doing something you could never film for real. Then check it frame by frame and fix the first thing that looks wrong. That's the whole process.

The AI Fight Scene Continuity Kit has everything to do it: the pipeline, fill-in-the-blank prompts with the real ones from this build, the lock sheet, and the free commands for checking every clip.

At the end of the day, the tool isn't the impressive part. Being picky is.
