觀諸近十年來的電影市場與票房紀錄，改編電影（尤其是小說改編而成的電影）有日益興盛的趨勢，本研究試圖從閱聽人的角度切入，初步探索小說改編的電影究竟對已閱讀過原著小說的「知情閱聽人」具有什麼樣的吸引力。研究發現，有別於缺乏原著小說「先備知識」的閱聽人，「知情閱聽人」的觀影動機主要來自對電影敘事中「未知」部分的好奇，以及對「已知」部分的再經驗慾望。此外，透過小說與電影兩種敘事文本與媒介特性的互文與互媒指涉參照，「知情觀影者」從中獲得感官性、情感性以及認知性的多重愉悅經驗。

In the past decade, a marked increase in the production volume and box office records of film adaptations of literature, especially those based on novels, has occurred in the film industry. Because of this phenomenon, the present study examined what makes novel-based films extremely appealing for viewers who have already read the novels (i.e., the knowing audience). It was discovered that curiosity regarding the novelty of the film adaptation and the desire to reexperience familiar content are the two strongest motivations that drive the knowing viewers to the movie theater. By watching such films, these viewers are able to experience multiple layers of pleasure—sensory, affective, cognitive, and reflective pleasures—caused by the intertextual and intermedial referencing and comparisons between the two formats, which is not attainable for people who watch the movie without foreknowledge of the source novel.
