The document discusses conventions of the post-apocalyptic genre in film. It notes that the genre depicts the end of the world through disasters that destroy modern civilization. Common conventions include survivors banding together, abandoned and dangerous settings with limited resources, and a focus on survival against deadly threats. The target audience is typically older teens and young adults who find themes of darkness and violence appealing. While many post-apocalyptic films follow conventions like community, isolation, and death, the author proposes a film with only two scientist survivors living in fear and accepting their new reality, with one eventually dying to the virus.
