ESSAY TOPIC:
Both films and novels are, among other things, forms of storytelling.
Compare Bram Stoker's Dracula novel with its cinematic adaptation "Bram Stoker's Dracula" 1992.
Your approach must reflect both the cultural/historical context of each version and formal differences between them.
Try not to restrict yourself to judgments based on unchallenged assumptions about fidelity, and bear in mind that, while two different forms of storytelling, novels and films are also very different media, and work in very different ways. Your essay should clearly reflect this awareness.
