Seeking advice: Best practices for using film content in modern PR campaigns?

I'm working on a project that involves using short film content to boost brand visibility, but I'm struggling with the strategy. It feels like there's a huge difference between making a cool movie and making a movie that actually achieves a measurable PR goal. Specifically, are there any guidelines for keeping the narrative engaging while ensuring the core message remains clear and authentic? I'm worried about the content feeling too forced or overly promotional. Any input from professionals who have successfully integrated cinematic storytelling into corporate PR would be greatly appreciated. Thanks in advance!
