Write the scene heading for the scene that contains the voiceover part in all caps. Include whether the scene is indoors (interior) or outdoors (exterior), the locations, and the time of day. For example: EXT. CENTRAL PARK - EARLY MORNING.
Write the action or stage direction, if there is any, that takes place just before or during the voiceover part. For example, "A couple on a bicycle for two rides past Maggie as she strolls through the park."
Write the character's name, followed by V.O. for voiceover in parentheses. Write the voiceover line beneath the character's name. Do not use quotation marks unless the character is quoting someone else. If this is the first appearance of the character in this scene, write her name in all caps. For example: MAGGIE (V.O.), Everywhere I go, I'm reminded of Jim.
