Supers - Titles, Signs, etc.
A Super is something that is superimposed over another thing. Sub-titles are supers. But, for your purposes, a Super is more likely some descriptive text like a time or location or a translation.
Supers are written with Action elements.. For example:INT. PENTAGON, WAR ROOM - DAYSUPER - 10:15 Zulu, Present TimeThe council gathers around the table.
What this means is that when we cut to the War Room, the words"10:15 Zulu, Present Time" will appear on the screen over the image of the council gathering.
Another example:Marty looks at the sign which is in Arabic.SUPER - Do Not Enter. Death Penalty Enforced.MARTY This must be the place.He walks in the door.
Some writers like to indicate when the film's title sequence should start and end by writing:BEGIN TITLESEND TITLES
My opinion? Don't bother. Let the director decide where the title sequence happens.
