All I have to say is...
IRON MAN, May 2008 -> Cameo: Nick Fury
HULK, June 2008 -> Cameo: Iron Man
IRON MAN 2, April 2010 -> Cameo: Thor
THOR, June 2010
CAPTAIN AMERICA: The First Avenger (Part 1), May 2011
THE AVENGERS (Part 2), July 2011

Buckle up. If they keep their track record and don't go all "Spiderman 3" on us, we'll have oodles of entertainment being served up piping hot.
