This document proposes developing the 2010 video game Heavy Rain into a feature film. Heavy Rain told the story of hunting for a serial killer through the perspectives of four playable characters. The game sold over 2 million copies and had a higher completion rate than most games. Adapting it to film would need to address fans' interest from the interactive experience and potential changes to the narrative. Conducting surveys of fans could provide guidance on casting, character focus, and maintaining interest in sequels. Emphasizing emotional engagement and appealing to new audiences in addition to fans would help the film's feasibility.
