5. 'Captain America: The First Avenger'
Release date: 2011
Director: Joe Johnston
Best moment: Cap's rescue of the missing platoon where he goes from PR stunt to genuine hero.
Legacy: There were certain things that were "common knowledge" as various studios tried to develop Marvel properties over the years. One thing I heard repeatedly from development people who talked about the pros and cons of the various properties was that no one would ever do a full-blown period piece version of "Captain America," and seeing that "wisdom" proved completely wrong was just one of the many pleasures of one of the most unabashedly exciting of the Marvel films.
