Radio3 produces a sound script, which matches the specification issued by BBC Radio 4. The template includes an automatic cast list and a place for typing your synopsis. All of the stage templates include an automatic cast of characters page. A second style for stage scripts, with the dialogue indented by roughly a third of the page width, and the Character Names left justified with just a small indent. Act headings are centred, Scene headings left justified.
Stage directions are italic and full page width.
This is similar to stage3b except that the character names are right justified within the left third of the page, to make them match more easily to the first line of dialogue. Scene Headings are centred and Stage directions in italic fill only the right two thirds of the page.
