dialogue
Stage directions in a script are in italics in order to set them apart from the dialogue. Italicizing aids the actors in that they do not speak the words in italics. Italics also draw attention to and aids actors and stage management persons including directors. lighting techs, prop persons and so on, to accomplish thier jobs on cue. Stage directions in general are given in a script for one of three reasons: 1) The author may add stage directions in order to clarify his intention in the movement of the story and his specific directions, when added, are added in italics to set them aside from dialogue. 2) If the play has already been produced and the script published, then the original director or cast members made choices in rehearsals and subsequently during performance which were then added to the original script when published. 3) Italics can be cues. Some more accomplished actors cross out all stage directions before memorizing a published script so as to free themselves from another actor's choices, instead using his/her own creativity to get from point A to point B in a performance.
