I couldn't help but notice the Hulk is a lot more smaller in the Avengers than he was in The Incredible Hulk. The normal characters are roughly reaching his shoulder while in the original movie they are reaching his waist size. Did someone else noticed that?
Hulk's size has never been all that consistent in the comics either if you think about it. Sometimes he'll seem to tower over every one while other times he'll be just barely taller then Cap. The old live action TV show was the only place Hulk's size was always the same.
