Screenplay

Definition
The screenplay is the written foundation of a film production, documenting dialogue, plot progression, and technical instructions in a standardized format. According to American standards (12pt Courier, specific margins), one page of a screenplay corresponds to approximately one minute of screen time, with a typical 90-minute feature film comprising 90-120 pages. The term evolved from the theatrical "role book" and became established with the industrialization of Hollywood in the 1920s.

Technical Details
Standard formatting is done in 12pt Courier New with specific indents: scene heading is left-aligned, action description has a 1.5" left margin, character name is centered at 3.7", dialogue is at 2.5" with a 2.5" right margin. Parentheticals (director's notes in parentheses) are at 3.1". Software such as Final Draft, WriterDuet, or Celtx automates this formatting. Distinctions are made between treatments (2-10 page summaries), step outlines (scene-by-scene breakdowns), first drafts, and shooting scripts with numbered scenes and revision colors.

History & Development
Thomas Ince developed the first standardized continuity scripts in 1912 at his New York Motion Picture Company. Frances Marion established the modern scene format with Master Scene Headings in 1915. The Hollywood standard crystallized in 1927 with the Academy of Motion Picture Arts and Sciences. Digital technology revolutionized the industry starting in 1995 with Final Draft, while cloud-based collaboration tools like WriterDuet have simplified international co-productions since 2013.

Practical Application in Film
Christopher Nolan's "Inception" (2010) demonstrates complex structuring with color-coded dream levels in the screenplay. Quentin Tarantino's scripts, such as "Pulp Fiction" (1994), deliberately use literary digressions beyond standard rules. Shooting scripts receive scene numbering (e.g., "47A" for subsequently inserted scenes), while continuity departments maintain script notes for matching corrections. Marvel Studios works with "Page One Rewrites" during ongoing production.

Comparison & Alternatives
Treatments focus on story without dialogue, whereas shooting scripts contain technical details for production. Documentaries use paper cuts or transcripts instead of traditional screenplays. TV series utilize writers' rooms and bible documents for continuity. Interactive media require branching scripts with multiple-choice structures, while VR productions develop 360-degree staging diagrams.
