Today's article is pretty short and simple. With the simple prompt I'll share below you can easily create your own action style poster with Nano Banana. Note: It will work to an extent with other models, but I find Nano's text is by far the most accurate. 

Nano Banana is a creative tool designed to help content creators generate high-quality visuals effortlessly. It simplifies the image creation process, allowing you to focus on what you do best—producing great content.

Below I'll run you through a few considerations and share the results.

To create a great Movie Style Poster with Nano Banana, start with this straightforward prompt:

Stylized Action movie poster,[Subject(describe the scene)], Title [Title],Subtitle [Subtitle] No other text, in complementary colors --v 6.0 --s 250 --ar 3:4 --raw

So depending on the use or intent that may work just fine for you. However, I typically have a more specialized intent and generally want to stay on brand. I'm not going to go into the hundreds of variables and ways we can tweak this to do that, but I will show you a few of the more pointed ones below. 

One of the first and probably most common desires would be to incorporate specific character/s into the image. This is easily done by adding an Omni Reference Image and then referencing that image in the prompt like I do in the 2 examples below. 

Stylized Action movie poster,The subject (Reference Image) stands in front of a grand skyscraper in a downtown city. He is dressed in a tuxedo and has black sunglasses on., title "Agent C", subtitle "No Content Is Safe", No other text, in complementary colors --v 6.0 --s 250 --ar 3:4 --raw

For some reason it decided to cartoon stylize that attempt. That is not always the case, but when it decides to do something odd like that you can easily correct it. Often times you can just run the generation again and it will work itself out. In this case rather than doing that I just added the word 'realistic' at the end of the prompt and it worked fine.
