Heavy Rain continues its slow progression from "like a movie with lots of button inputs" to "just a movie." Deadline reports that Unique Features is in the process of acquiring the film rights to Quantic Dream's game. Unique Features is a production company started by Bob Shaye and Michael Lynne, who used to be with New Line, the studio that had optioned the rights to the game in 2006.
Shaye and Lynne are apparently so interested in the project that they bought the rights with their own money. Maybe the game was too hard for them and they just wanted to see how it ends.
