I saw in an interview by Azazel's actor that he had a whole bunch of ideas in mind for Azazel's character that influenced the way he acted. In the sequel, he hopes to be able to really show off this characterization.
yhea.they didnt screw with the caracters so muthc,but i havent read the comics alot so i woundnt know,but from what ive heard,azezel wouldnt follow shaw like he did.ah,well.good movie tho.
