The random superhero may be Ant-Man. He was on the Avengers in the comics, but I didn't think he would be in the movie, due to him being very uninteresting. The second person from Iron Man is War Machine, played by Don Cheadle, who replaced Terrence Howard in Iron Man 2. The other person from Thor will be Loki, who I mentioned earlier in the post. He has been confirmed to appear, but I don't think he will be a villain. The guy to replace Edward Norton as the Hulk is Mark Ruffalo. He will be the first to actually "be" the Hulk. The Hulk is usually CGI, but they will use motion capture so Mark Ruffalo can actually be the Hulk.
