I usually reach for a simple word: 'setting'. It reads cleanly on the page and plays well with sluglines like INT./EXT., but that doesn't mean it's the only option. For a more visual punch I often use 'backdrop' when the location is acting almost like a character — a stormy coastline as a backdrop to a breakup, for instance. 'Landscape' or 'vista' works when you want to evoke scale and sweep: they tell the reader to imagine space and distance, which helps the director or DP think about wide lenses and slow dollies.
If I'm trying to be deliberately cinematic and slightly more technical, I lean on 'mise-en-scène' to capture not just physical scenery but the arrangement of props, actors, light and motion. Use it sparingly in scripts meant for producers who prefer plain English, but it's gold in director-driven treatments. For tight shooting scripts, choose clarity: 'locale' for practical place identification, 'terrain' for physicality and obstacles, and 'tableau' when you want a staged, painterly image. Personally, balancing precision with a little evocative flavor gives scripts the right emotional cues without slowing down production — I like that happy middle ground.
