Which contributors should I mention in a Chicago film citation?
The director should always be listed in the author position in a Chicago film citation, followed by the label “director.” Other contributors to the film (actors, cinematographers, writers, composers, producers, etc.) may be listed after the film title, e.g. “Featuring Willem Dafoe and Robert Pattinson. Cinematography by Jarin Blaschke.”
Only the contributors relevant to your discussion of the film should be added. You might mention actors whose performances are discussed in detail, or the composer if the use of music in the film is examined. It’s also fine to mention no contributors other than the director, if none are relevant to your discussion.
