Not all Marvel movies share continuity with one another. And I'm not just talking about the Ray Stevenson Punisher, here. It also affects the X-men and Spider-man franchises. The Marvel Cinematic Universe consists of these (and only) these films:
The Incredible Hulk
Iron Man 2
Captain America: The First Avenger
Because the X-Men and Spider-man films don't share continuity with the MCU, I didn't use the AOS tag "Marvel (Movies)" which encompasses ALL the movies, not just the MCU.
That ought to make it clear as mud, I figure. ;)
