Because he is not an avenger!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
In the comic books? Yes. Sometimes. In the movies? Not yet.
Because Sony is in charge of Andrew Garfield and the directors of the avengers are not sure yet to let Spiderman in its a 10% chance that he will be in it
Spiderman, Spiderman 2, Spiderman 3, and recently the Amazing Spiderman
Tobey Maguire is not going to be in any more Spiderman movies. They are remaking the Spiderman movies using a new actor (Andrew Garfield) playing Spiderman with an entirely new cast.
THE Avengers 3
Robert Downey Jr. (man that plays Iornman) agreed to only 3 Ironman movies but he will also be doing a movie called "The Avengers" soon so you could count that as his fourth movie. In the Avengers there gonna make Thor, Ironman, Hulk, Captain America, and possibly Spiderman be in the movie. It will probably come out in 2011 or 2012 though.
Spiderman is a fictional comic book hero and does not make movies.
