So I'm working on writing a script and had a question about a slug line. I start off the scene on a floating ship, then move to the ocean floor, where the action stays. (Think of a swordfight between two skeletons that starts on a ship and continues underwater.) Would I just use: EXT. OCEAN - DAY ...and keep that heading all the way through or would I change the scene to something like: EXT. OCEAN FLOOR - DAY Thanks. ~ J. J.
