This workflow takes an existing movie, and turns it into a movie of another genre. In the example, it turns it into a horror movie poster.

It uses a few custom nodes, like a Groq LLM node, to come up with movie posters ideas based a list of user-defined genres. This node requires you to set up a free account with groq, and to create your own API key token, and enter this in the \ComfyUI\custom_nodes\ComfyUI-mnemic-nodes\nodes\groq\GroqConfig.ini

I recommend using Llama3-70b as the LLM model.

The other nodes in there are optional and just my preferences.

This list could be swapped out for a list of movies instead.

Feel free to swap out any save image, text preview or wildcard loader prompt node to whatever you want.
