For you readers or otherwise, where do you stand? When you prepare to watch a film adaptation of a literary work, or, before you read a book that has an adaptation to film, what goes through your mind? Which comes first?
For me, this isn't any sort of question of "which medium do I have a special proclivity towards at the time," but merely which process allows me to be the most unaffected in my analysis of both works. I've chosen "movie first" because the combination of the time and imagination dedicated to reading a novel doesn't compare to the brief running time and offered images of a film.
