for all the old timers:
movies are based on the ultimate line of avengers.
ultimate line: a new comic line of several years ago, stating off from scratch. sort of a test to see what fanservice and extremes could do for sales. instead of average sales that avengers normal generate, it beat x-men numbers. in this universe, nick fury is a black man. besides, i hear that the nick fury we know and love retired anyway in the "normal" line of comics.
a awesome cartoon movie was made of the first story of the ultimate avengers, so you can get a taste of how things are to be, since the ultimate line outsells everything, the normal lineup slowly disappears and is replaced by all ultimate versions. get used to it.
