Yeah, wasn’t the Rogue One trailer an example of this? I recall there was a scene where the main character comes face to face with an airborne tie fighter - the entire sequence was absent from the film. According to the director, the scene had no connection to the story and never had any chance of making it into the film. It was just a visual idea the marketing team really liked.

Interesting, maybe I’ll read that before re-watching the film. Thanks for the recommendation!

I’d like to watch this and Annihilation again. I’ve only seen each of them once, both around the same time, and my memories of them are pretty fuzzy at this stage.
