Lookbook Before Budget: Building an Indie Film Visual Package With Nano Banana Pro — and Where It Has to Stop

Every indie feature goes through the same stretch: the script is finished, the pitch meeting is booked, and there is no money to shoot a frame. Producers, festival labs, and private investors all want to see the film before they fund it. What they get instead is a PDF of screenshots from other people’s movies, a Pinterest board, and a director explaining in words what the thing will look like.

Generative image tools have closed that gap faster than any other part of low-budget filmmaking. A director can now build a lookbook, a set of concept stills, storyboard frames, and poster comps in a weekend, with a consistent palette and a consistent lead character across all of them. The reference-driven models in the Nano Banana family are built for exactly that part of the job — holding one face, one costume, one light across dozens of frames — with Nano Banana Pro carrying the higher-resolution output you want for anything that will be printed or projected in a pitch. A mood board of borrowed screenshots does none of this.

The tools also make it trivially easy to produce material that will end you in a legal conversation, get a festival submission pulled, or sour a cast member before the first table read. The useful skill is not prompting. It is knowing which documents in the package may be generated and which must not.

What a Visual Package Contains, and Who Sees It

• Mood board / tone reel stills
  • Audience: Internal, HODs
  • AI-generated?: Yes
  • Must be real: Nothing
• Lookbook (palette, light, texture)
  • Audience: Producers, financiers
  • AI-generated?: Yes
  • Must be real: Nothing
• Concept stills of key scenes
  • Audience: Investors, sales agents
  • AI-generated?: Yes, labeled
  • Must be real: Nothing
• Storyboards / previz frames
  • Audience: Crew, DP, 1st AD
  • AI-generated?: Yes
  • Must be real: Blocking must match the real location
• Location scout package
  • Audience: Producers, line producer
  • AI-generated?: No
  • Must be real: Photographs of the actual location
• Cast presentation
  • Audience: Financiers, casting
  • AI-generated?: No
  • Must be real: Real headshots of real attached actors
• Poster comp for the deck
  • Audience: Internal, sales
  • AI-generated?: Image yes, type no
  • Must be real: Credits, laurels, billing block
• Festival submission materials
  • Audience: Programmers
  • AI-generated?: Follow each festival’s rules
  • Must be real: Stills from the finished film

The pattern is simple. Anything describing intent can be generated. Anything asserting a fact — this location is secured, this actor is attached, this festival selected us, this is a frame from the film — cannot.

Lock the Look Before You Generate a Single Frame

The mistake most first-time users make is generating forty beautiful images in forty different films. A lookbook’s whole job is to prove that a coherent visual system exists in the director’s head.

Decide five things first, in writing, before any prompt:

1. Palette — three to five colors, named. “Desaturated teal, sodium orange, dirty white.”
2. Light — the dominant source and its quality. “Practical-lit interiors, hard single-source daylight outdoors, no fill.”
3. Lens and framing — “40mm, mostly mediums and wides, subject small in frame.”
4. Era and texture — “Late-90s, 35mm grain, slight halation on highlights.”
5. World rules — weather, density, wear. “Always overcast, always wet asphalt, nothing new-looking.”

Then generate two or three images that nail all five, and treat those as the style references for everything after. From there, every new frame points back to them. This is how you get thirty images that look like one film instead of one mood board per scene.

Holding a Character Across Thirty Frames

Character consistency is where most decks fall apart — the protagonist ages ten years between page four and page nine, and the costume changes color.

Build a character sheet first: one frontal, one three-quarter, one profile, at the same light and same costume. Lock it before generating a single narrative frame. When you work in Nano Banana AI, feed that sheet plus your style reference together, and describe only what changes in the new frame — the location, the action, the time of day. Keep the face, hair, costume, and build in the “do not change” half of the prompt every time, even when it feels redundant.

One important constraint: the character sheet should not be built from a real actor’s photographs, and the generated face should not resemble a specific performer you hope to attach. More on that below.

Prompt It Like a Shot List, Not a Vibe

• Vague:
  “Cinematic shot of a lonely woman in a diner, moody, 8k”
• Usable:
  “Wide shot, 40mm, character from reference sheet seated at the window booth of a night diner. Practical fluorescent overhead, sodium streetlight through glass. Desaturated teal and orange palette, 35mm grain. She is small in frame, right third. No text, no signage.”
• Vague:
  “Make a dramatic poster for my thriller”
• Usable:
  “Vertical one-sheet composition. Character from reference sheet in silhouette at the center-bottom, facing away, on wet asphalt. Empty upper two-thirds, flat overcast sky, room for a title. No text anywhere in the image.”

Two habits raise the hit rate more than anything else: one job per generation, and always specify the frame ratio and where the empty space goes. A gorgeous concept still that has no room for the title is not a poster comp.

The Four Things That Must Never Be Generated

1. A recognizable actor’s likeness. Not for a “dream casting” slide, not for a lookbook, not internally. Generating a named performer’s face to suggest attachment raises right-of-publicity problems, and it is also a bad look to the actor’s representation when the deck leaks — which decks do.
2. Anything implying the film exists. Generated “stills from the film” presented without labeling, fabricated behind-the-scenes photos, or invented festival laurels. Fake laurels alone have gotten films disqualified and filmmakers publicly named.
3. The credits block, billing block, or any poster text. Image models still produce letterforms that fall apart at readable size, and a misspelled distributor name in a comp that reaches a sales agent is not a typo, it is a credibility problem. Generate the image; set every letter in a design tool.
4. A real, unsecured location shown as yours. Generating a recognizable building, landmark, or venue in your deck tells a line producer it is available. Scout photos are the document for that.

Label It, Once, Clearly

One line on the lookbook’s title page does the whole job: “All visual material in this document is AI-generated concept art indicating tone and intent. No footage has been shot. No cast is depicted.”

Producers and programmers are not hostile to generated concept art — they are hostile to being misled about what stage a project is at. Also check each festival’s and each grant body’s current AI-disclosure rules before submitting anything; several have added specific language in the past two years, and they are not identical.

Conclusion

Generated imagery solves the oldest problem in independent film: proving a vision exists before anyone will pay for it. Lock five style rules, build one character sheet, point every frame back at those references, and put type on top in a design tool. Then draw the line at the documents that assert facts — cast, locations, footage, selections — because those are the ones that get a film pulled from a festival, not the ones that get it financed. A lookbook that looks like one film and tells the truth about its stage will outperform a beautiful deck that overclaims, every time.
