By film based fiction i assume you mean books written based on films, not books that have been made into films, otherwise I read whatever interests me whether it's a movie or not. Generally books that have been made into films don't interest me (except for Fight Club, but I haven't been able to find a copy, not that I'm trying really hard)
I have no interest what so ever in game fiction
Currently reading The Gunslinger by Stephan king (excellent book, there's the next two at the 2nd hand bookstore, hopefully they're still there when I get paid) and I've been meaning to read Filth by Irvine Welsh (which I admit, I picked up because of Trainspotting), but I'm not very good at managing my time for reading
I also bought Welcome to the NHK after seeing the series (the novel that is, not the manga (tho I do have the first manga volume too(I haven't bought manga in years))), so I guess there are exceptions sometimes
