Where, when, and who are the three primary components of scene-setting in a script. For example:

''INT. WOLFRAM & HART - HALLWAY (where)- MORNING (when)

ON ILLYRIA (who)...''

Words like these in a script suggest to a director what is important about the scene, and -- if the director agrees -- help to cause the scene to be rendered in the way the author imagined it would have been.

Note that WhereWhenWho might sometimes be where, when, and ''what'', rather than ''who''. An example from the same ''Series/{{Angel}}'' script:

'' INT. RACQUETBALL COURT - EVENING

CLOSE ON a white wall for an instant...''

This helps the audience understand a change of scene by emphasizing the ''where'' of the scene. A quick visual transition to the ''who'' in the new setting is mandatory, unless the place is more interesting than the people.

Beseech the deity of your choice for mercy, O Writer, if the places are more important than the people.
