A theatrical one-sheet has four parts: key art that sets the mood, a title in a custom letter style, a tagline that teases the conflict and a billing block of credits. An AI movie poster generator has to get all four right in one image, and the lettering is the hard part, because a misspelled title ruins the illusion.
That is why this page starts on GPT Image 2.5, the model on our site that follows long prompts most closely and keeps words readable. When the star is a real friend, a Nano Banana model usually keeps the face closer to their photo. The free FLUX.2 model is fine for key art without text.
New accounts get 8 free credits, then 4 more every day from the second day. With GPT Image 2.5 a poster costs 3 credits at 1K, 4 at 2K and 7 at 4K; the exact cost shows before anything is spent.
Your AI movie posters save privately to My Images, download without a watermark and may be used commercially, for example to promote your own film. Keep them original: no real movie titles, actors, studio logos or franchise characters, and no sexual content, minors or images meant to deceive or harass.
