Start the scene by typing the scene location and information in uppercase letters and underlining the description. To describe an interior scene write "INT." For an exterior scene write "EXT." Write the location of the scene followed by the time of day. For example:
"INT. MUSEUM OF ART, HALLWAY -- DAY"
or
"EXT. MUSEUM OF ART, FRONT ENTRANCE -- MORNING"
Double-space after the scene introduction, and write beginning action of the scene. To do so, create a left parenthetical. Write out all of the action in uppercase letters. Close the action by placing a right parenthetical. For example,
(CHILDREN RUN PAST THOMAS SMITH, 25, CHILD ONE, 10, BUMPS INTO THOMAS CAUSING THOMAS TO BRUSH AGAINST A VASE.)
Always describe the character by his/her name, and the first time the character is mentioned place his/her age immediately after the name.
Double-space after finishing the action, and continue with the script.
