Philadelphia, Pennsylvania is significant to the Frankenstein film because this is the birthplace of one of the most prestigious fantasy and horror film screenwriters of Hollywood, who also helped to tweak the film - John L. Balderston. While he is best known for his play adaptation of the Universal Monster Dracula, he majorly contributed to Frankenstein's development on screen. I found this information from an academic article by Concord Theatricals. This source is an example of collective authorship via platform as gatekeeper because Concord Theatricals is a major theatre company, where various credible authors have been vetted to provide information about different screenings, plays, and films. Mapping this location on COVE adds a grassroots layer to Frankenstein because recognizing the contributors to the screening plays a major role in understanding certain elements of the film's story.
