Half of Godfather part II is a prequal... so what if the other half was a sequal? Never knew the play Casablanca was never produced though... interesting. Only knew it was based on a play (though one could argue this would be like adapting in Star Wars Underworlds or 1313, both of which never saw the light of day either) As to some of the listed comic films not following story lines, some may not have followed specfic story lines but they all followed trends for those characters. All phase one was an adaptation of origin stories and both phases used many times over previous adapted characters (thus still qualifying for adapted script)... and all the Nolan Batman movies adapted in basic character origins... which was my point of listing them, the list wasn't soley about adapted stories but partaining to what I viewed as ways to view EU characters getting adapted in rather than full stories being adapted. My list was aimed at showing different types of adaptations, not just the 'classical' way to define an adaptation but include many more new ways it would count today too.
