That is one of the reasons I was surprised to see C/E fic that seemed to be movie based. (I say seems because I haven't read it yet.)
Most of my stuff is half movie, half bookverse, but that one is mostly movie based.
I phrased that badly. I meant that I hadn't really read C/E fic. When I read the books as a kid I didn't see it- I saw any romance as icky when I was eight- and in the films we didn't see enough of Edmund and Caspian interacting for it to spark my interest. If they ever get around to filming and releasing VODT I might.
