Did you like it when Captain America's shield was seen in Stark's lab in the Iron Man movie? What about Stark making a cameo in the Hulk movie? If you enjoy these inter-universe cameos spread across the Marvel comic movies, you'll probably appreciate the fact that Thor's director has been asked to do some similar stuff. Marvel's editor-in-chief Joe Quesada said:

"He was really, really loving the interconnectivity between all of these characters and even thinking ahead as to how does Thor interrelate with the Iron Man movies. How will he interrelate with the The Avengers movies, and how do we set these things up."
