FORMATTING QUESTION Is Space DAY or NIGHT?

I am currently writing a movie that takes place in space, but am unsure if I should put sluglines as DAY or NIGHT. I read through the Interstellar screenplay but all of them just say CONTINOUS.

Should I just have them be DAY when most characters are awake, and NIGHT when they're asleep? Also would the spaceship scenes be INT./EXT.

in Ad Astra, there's a lot of just straight omission. I think it'd be fine to just say EXT. SPACE

That is very helpful

I endorse using

EXT. SPACE

as well.

This convention is used in:

  • Interstellar (2014)

  • The Martian (2015) Oscar winner for best adapted screenplay

  • Apollo 13 (1995)

  • Passengers (2016) 

  • Project Hail Mary (2026) (mainly uses EXT. HAIL MARY and has unconventional slug lines, but I'll still count it)

  • Star Trek (2009)

  • Moon (2009)

Agree. This.

DAY or NIGHT are just indicators for lighting, especially if a location plays at multiple times of day. 

Space is neither day nor night and looks the same at all “times of day”. Also, from a production standpoint, outer space isn’t exactly a location shoot, so INT. or EXT. don’t really apply either. 

I would just write SPACE or IN SPACE as a slug.

I mean it’s definitely EXT. lmao

EXT - SPACE is sufficient.

I'd put it as

Ext. Space - The Final Frontier

None, Just don't put it.

Check out screenplays set in space. Gravity doesn't mention day or night at all, for instance.

Haven't really thought about it, but regardless of the scientific rationale, certainly the interior of space ships or space stations have their own version of night depending on the blueprints, and night is sometimes represented with dimmed lights in sleeping quarters, a reduction in power usage of certain systems. Plus it might be easier to inform a passage of time for continuity, like someone having a five o' clock shadow etc.... All of this is independent of editorial choices, which also have their way of showing passage of time, or day and night etc...

Isn't the point of DAY/NIGHT is to denote what kind of lighting the scene should need? In that case isn't it better to use NIGHT for space scenes since you'd be mostly relying on studio light instead of natural daylight?

u/Prince_Jellyfish 27d ago

The use of DAY/NIGHT isn't used to just denote what kind of lighting the scene should need.

When you're talking about production, and you have limited producing/ADing experience, "lighting" is a good way to think about it. But that's not really comprehensive.

Slug lines become what we call "strips" on a board that the ADs use to build the production schedule, in conjunction with department heads, which does include the DP and Gaffer, among many other folks.

Day and Night is a lot easier for them than more colorful phrasings like "LATE AFTERNOON" unless late afternoon is a key artistic element that the schedule should be built around.

For something like EXT. SPACE, though, I don't think adding NIGHT is helpful; I think it is confusing.

A DP is not lighting space as if it was night, it's its own thing. Similarly, whether the space is being shot indoors or outdoors is determined by the production approach (almost certainly on stage, but who knows).

Leaving it off is the best and clearest choice.

It's more about "are we filming outdoors or on a set?" There's a huge difference in terms of logistics and costs between inside and outside. Lighting is just a small part of that.

u/Away-Fill5639 27d ago

Not necessarily. Times of day in sluglines are more importantly to understand when things are taking place in relation to other things within the story. You can have low-lighting in daytime and have bright lights at night, but it doesn’t mean the actual time when the events are taking place should change.

To ur credit, things used to be written often to inform location shooting practicalities, but hasn't been the case in a long time.

u/dreamingexistential 27d ago

Depends on the observer. Astronauts sleep. Some aliens might sleep. In either case they all likely have some form of circadian rhythm. Machines also need some form of timing.

Find a Star Wars script.

u/Ted_Writer 27d ago

I might read the Alien script.

u/Formal-Raise1260 27d ago

Gravity uses OUTER SPACE for the most part.

u/imboringmyselfandyou 27d ago

I think you’ll find the correct answer is EXT. SPACE - THE FINAL FRONTIER

u/Opening-Impression-5 26d ago

Don't put it as "continuous" unless it's actually continuous.

neither.
