Cite the name of the film in italics if you are using MLA style. For example:
A classic film villain once stated: "I'm gonna make him an offer he won't refuse" (The Godfather).
However, if you are going to begin your works-cited entry with the last name of an actor or director in order to emphasize their work, you should cite that person's last name instead of the name of the film. For example:
A classic film villain once stated: "I'm gonna make him an offer he won't refuse" (Brando).
Cite the last name of the film's producer and the year the film was released if you are using APA style. Separate these elements with a comma. For example:
A classic film villain once stated: "I'm gonna make him an offer he won't refuse" (Ruddy, 1972).
List film details in a footnote if you are using Chicago style. Your footnote should follow this template:
Footnote Number. Title of Film (in italics), directed by First Last (Year of Original Release; City, State in which studio is located: Name of Studio, Year of DVD or Video Release), Format of Release.
For example:
1. The Godfather, directed by Francis F. Coppola (1972; Los Angeles, CA: Paramount Pictures, 1997), DVD.
