The document discusses the development of a thriller opening sequence created by the author and their group. They began with several ideas taken from other thrillers, including one about hallucinations from The Exorcism of Emily Rose. Their final idea involved a group of teenagers on a train that has a power outage. The opening sequence uses conventions from thrillers like The Blair Witch Project and Creep. It targets an audience of 16-25 year olds and would be distributed first to smaller media companies to gather feedback before approaching larger companies.
