I’ve been seeing this mistake a lot lately in the scripts I’ve been proofreading. The writer will use SAME when they mean CONTINUOUS. They are not the same thing and have very different uses.

SAME TIME

SAME (sometimes written as SAME TIME) means that the scene occurs at the same time as the previous scene. That is, the actions and dialogue taking place in this scene occur while the actions and dialogue from the previous scene are occurring.

CONTINUOUS

CONTINUOUS means that everything occurring in the scene takes place immediately after the previous scene, with no gap in time (otherwise MOMENTS LATER/LATER/DAY/NIGHT would be used).

Putting it all together

It’s rare to need SAME in your scene heading. An example of a legitimate use would be as follows:

EXT. DODGE CITY - MAIN STREET - DAY

Rival SHOPKEEPERS glare at each other from across the street.

Shopkeeper 1 gives Shopkeeper 2 the middle finger. A fuse has
been lit. Both Shopkeepers dash into their respective stores.

INT. SHOPKEEPER 1'S STORE - CONTINUOUS

Racing behind a counter, Shopkeeper 1 opens a drawer, pulls
out a revolver, blazes back to the front door. 

INT. SHOPKEEPER 2'S STORE - SAME

Sprinting to a cupboard, Shopkeeper 1 quickly unlocks it,
removes a long rifle, runs back to the main entrance.

EXT. DODGE CITY - MAIN STREET - CONTINUOUS

Both Shopkeepers emerge from their front doors simultaneously,
aim their guns. 

CLICK. 

CLICK.

Both guns -- empty.

Side note

In modern spec scripts, using CONTINUOUS is optional. You can just leave it blank if the scene is occurring immediately after the previous one (e.g. EXT. SHOPKEEPER 1’S STORE would have been satisfactory in the previous example). Just make sure you’re consistent. Don’t leave it blank sometimes and other times use CONTINUOUS.

It’s also just fine to use the standard DAY or NIGHT instead of CONTINUOUS. We’ll understand there’s no gap in time from the context of the scene — the same way the audience will.

What heading or formatting elements trip you up?
