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.
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 (2009) and its notoriety caused the spread of the term.
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.
