Notes: 

You may include any contributors you deem necessary such as but not limited to performer(s), director(s), producer(s), screenwriter(s), or creator(s). When the title of the film is in the first position place the function of the contributor before the name (e.g. Directed by Yavar Abbas). Contributors should appear between the title of the film and the distributor and must be preceded with an appropriate function. If you are emphasizing the contributions of a specific individual, begin the citation with that person's name (see second example) (MLA 24). For in-text citations, you can use a time-range instead of a page number as demonstrated above (MLA 57).
