 In November 2011 , Marvel announced that Alan Silvestri , who scored Captain America : The First Avenger , would write and compose the score for The Avengers . Silvestri said , " I 've worked on films where there have been a number of stars and certainly worked on films where there have been characters of equal weight in terms of their level of importance and profile in the film , but this one is somewhat extreme in that regard because each of these characters has their own world and it 's a very different situation . It 's very challenging to look for a way to give everyone the weight and consideration they need , but at the same time the film is really about the coming together of these characters , which implies that there is this entity called the Avengers which really has to be representative of all of them together . " Silvestri developed the score with the London Symphony Orchestra at Abbey Road Studios in London , England . Whedon said , " The score is very old @-@ fashioned , which is why [ Silvestri ] was letter @-@ perfect for this movie because he can give you the heightened emotion , the [ Hans Zimmer ] school of ' I 'm just feeling a lot right now ! ' but he can also be extraordinarily cue and character specific , which I love . "
