The summer of 2011 has been called the Summer of Superhero Films. In early May we had Marvel Studios’ Thor film premiere to good reviews and it has had a certain level of success (though not the level of The Dark Knight success rabid fanboys and jaded film bloggers think every comic book-based film should be doing). Then next up was the fourth X-Men film from Twentieth Century Fox by Matthew Vaughn that seem to reboot the franchise from it’s downward spiral begun by the third film and the Wolverine origins film. This film garnered even higher praise than Thor and many saw it as equaling or surpassing the X2. While it’s box-office success has been good it didn’t make the sort of money previous films in the franchise have made in years past. Then we come to the recently released Green Lantern from Warner Brothers and DC Entertainment.

This film was to be the next crown jewel to join DC’s successful Batman film franchise and iconic Superman series which seems to be the only DC properties to have had a successful live-action adaptation. While the film did very good in it’s first weekend the reviews of the film range from “ok and fun” at best to “downright awful” at its worst. All three films have huge budgets and, most likely, all three will be a profit for their studios, but not runaway hits.

Maybe the public has begun to tire of superhero films as a cause for the less than cosmic box-office returns. One other reason could be that too many people have been blinded by the massive box-office success of Christopher Nolan’s The Dark Knight that every superhero film must now be compared to that one fair or not. This makes the job much harder for Marvel Studios’ second film of the summer, Captain America: The First Avenger, as that film looks to cement the foundation for next summer’s major blockbuster ensemble superhero film, The Avengers.

I don’t see Captain America doing TDK level money, but early screenings of the film has earned it some major positive buzz that had been missing from Thor. That early positive buzz and this latest trailer which really showcases the action of this period piece of a superhero film should help push Captain America to be a success no matter if it makes 200million dollars domestic or more.

One thing I’m sure of is that this latest trailer should be more people excited for Captain America: The First Avenger when it comes out on July 22, 2011.
