An author is "the person or group primarily responsible for producing the work" (MLA Citation Style Guide 22). An author can be a person, persons, or an organization who created the work that you are citing.
If your research paper / project focuses on the contributions of a specific person (actor, screenwriter, singer, choreographer, etc.), use the name or online name of that person.
For media citations, the title of a source can be an episode title of a TV show, a song, etc.
Format source titles appropriately with quotation marks. A container title is placed in in italics.
In MLA Citation Style, a container is considered to be "a larger whole . . . that holds a source" (30). It is a larger source that contains smaller works.
For media, a container would be the title of TV series, the name of an album, etc.
If you are citing a TV series watched through a subscription service, like Netflix or Hulu, however, make sure that you also cite this service. See the Two Containers example above.
For media citations, the "Other Contributor" field is where you put people who helped contribute to the source and are relevant to your paper.
See the MLA Citation Guide page 38 for other examples.
If the source you are citing exists in multiple versions, include the version that you are using in this field. For example, the film you are citing might be the director's cut.
Sources may be part of a numbered series, like issues of journals, graphic novels, or episodes of TV shows.
For media, this would be a the season and episode number for a TV series.
For media, cite the organization that has the "primary overall responsibility" for the work.
When citing a source with more than one publication date, cite the date that is "most relevant to your use of the source" (42).
For media, if possible, use the broadcast date or year for TV series; the day the album was released; the day the movie opened in theaters.
Location is defined by the type of source you are citing.
If you are citing a a TV series from a DVD set, use the disc number as location; the url if you are citing a YouTube video; etc.
