Scriptment
A scriptment is a written work by a movie or television screenwriter that combines elements of a script and treatment, especially the dialogue elements, which are formatted the same as in a screenplay. It is a more elaborate document than a standard draft treatment. Some films have been shot using only a scriptment. Origin. The term "scriptment" was originally coined by filmmaker James Cameron, possibly during his early involvement in the development of the "Spider-Man" film series. In that effort, after the success of his 1984 film "The Terminator", Cameron wrote a 57-page scriptment for the first  proposed "Spider-Man" film, which was used by screenwriter David Koepp to write the first draft, incorporating it nearly word for word. Cameron's scriptment for "Titanic" (1997) was 131 pages. The term became more widely known when Cameron's 1994 scriptment for the 2009 film "Avatar" was leaked on the internet during pre-production, although other directors, such as John Hughes and Zak Penn, had written scriptments before. The scriptment for "Avatar" and its notoriety caused the spread of the term. Elements. A scriptment borrows characteristics from both a regular screenplay and a film treatment and is comparable to  a step outline: the main text body is similar to an elaborate draft treatment, while usually only major sequences receive scene location headings (slug lines), which is different from the extensive slug line formatting in standard screenplays, where every new scene or shot begins with an INT./EXT. DAY/NIGHT slug line set above the description or dialogue. However, just as a treatment can be short or long, a scriptment can exist in various degrees of completion depending on how much time the writer has devoted to it and a more fully developed one could have all slug lines in place , a great deal of dialogue, and only require the producer's (or a writing partner's) okay on the direction the finished script should take before proceeding further. In a scriptment, scenes and shots may be separated as paragraphs or sentences and, if it is the writer's style, can also include an occasional explanatory note, such as might be important in an adaptation or a sequel. As with standard treatments, much of the dialogue is summarized in action. The longer the scriptment, however, the more likely it contains dialog scenes that are fully developed. Single words or brief phrases  of dialogue can be included within the description and lengthier exchanges are formatted exactly as a regular screenplay, which is the main reason for the "script" part of the term. The longer the scriptment, the more likely it is written shot to shot as opposed to scene by scene; thus, a long, detailed scriptment does not necessarily equate to a longer movie, as a typical 90-120 page screenplay written with master scenes contains many more individual shots than are immediately apparent. A scriptment can begin with FADE IN: top left and conclude with a centered THE END. It can  have a title page like a script and lengthier treatment. It is written single spaced with an empty space between paragraphs and other elements and the pages are numbered in the upper right corner, just as in a screenplay. Work-in-progress manuscript. Directors and screenwriters write scriptments as an intermediate stage in development from the draft treatment to the first draft of the screenplay. Like a draft treatment, a scriptment can be anywhere from 20 to 80 or more pages, while regular presentation treatments or outlines only summarize the plot, typically in not more than 30 pages. Presentation manuscript . A scriptment can also be a presentation document; that is, one that is sold or handed in as the finished work.
