Hey guys.

I’ve done this when a character walks into a house...
EXT./INT. HOUSE - day
BEDROOM

That is clear, that we’re following him, right? Or at least get a shot outside and in.

Same goes I’ve got a scene that cuts between inside and outside of a place. I’ve done this.

EXT. /INT. LOG CABIN - night
INSIDE
OUTSIDE
WOODS - SAME TIME.

We begin inside the cabin then move between inside and outside.

I love my secondary headlines but I swear I get carried away/overabuse them.

Not remotely correct, sorry to say.

You can't use INT and EXT together...unless you're "cheating" and using it in a car scene...basically saying, "you decide how to shoot this".

The whole point of INT and EXT in a Slug is so it can be filmed and planned correctly, with lighting and the like.

It sounds like you're after some kind of tracking shot, which is tough to pull off and not your job in a Spec script.

About the only place I use INT/EXT is in my car scenes where the camera placement is both inside and outside of the car. Guess it could be used other places but that is where I've used it best.

The "proper" use for EXT/INT. is when the camera starts outside the structure and dollies/steadicams inside.

The only place I've felt comfortable using it was in the slugline for a montage that had some indoor shots and some outdoor ones.

I agree with Dreamscale. If you start outside then use an EXT heading. If you then go inside, it's a new heading starting with INT.

I'm so glad I asked.

I've done some research and the only other place you can do it is certain situations like... a phone booth or when someone opens a window. And yeah - car scenes.

Okay thanks guys.

Hmmm.

Could I still do this?

INT. LOG CABIN - night
INSIDE
OUTSIDE
INSIDE

Also. I recently wrote an action scene when a man chases another man through the street and did this...

EXT. STREET
POLICE CAR
STREET

I swear you can get away with that one.

Another thing with sub headings I've been thinking about is time.

We don't have to put in "same time", "moments later" unless absolutely necessary, right?
I read a script where the couple have sex in every part of the house and it just skipped the "moments later".

There was no action line to connect one place to another.
There was no "so-so move to the kitchen", "so-so moved to the tv room". It just skipped.

Quoted from The Dark Horse We don't have to put in "same time", "moments later" unless absolutely necessary, right? I read a script where the couple have sex in every part of the house and it just skipped the "moments later".

That's correct. So long as it is clear then you can do as you please. If it flows better not using something, don't use it.

Thanks Dustin. You've been a huge help.

I've recently become a lot more confident about using "Morning" and "Sunset" in headings too. I think it helps paint the picture. Especially if time is significant.

I changed this from...
INT. LOG CABIN - night
INSIDE
OUTSIDE
INSIDE

to
INT. LOG CABIN - night
EXT. LOG CABIN - night
INT. LOG CABIN - same time
EXT. LOG CABIN - night
EXT. THE WOODS - same time

Perhaps not as fluid but still abides by the rules of INT./EXT. and I don't look amateur.

My theory about STREET subheadings is correct right?
As CARS are technically a prop or in the street. Same as a phone booth. So we can do this...
EXT. STREET
COP CAR
STREET
PHONE BOOTH

When you say "SAME", I think you actually mean, "CONTINUOUS".

EXT, LOG CABIN - NIGHT

John watches the woods intently.

INT. CABIN - CONTINUOUS

Mary stares nervously at the front door, shotgun in hand.

Hi Dreamscale.

Yeah. You're right. I think "same" has to be EXACTLY the same time. I'm probably best with "continuous" or moments later.
