Summer 2014 already is jam-packed with comic book and action fare. The Amazing Spider-Man sequel is set to open May 2, followed by Dawn of the Planet of the Apes on May 23. Late June brings Transformers 4, while the untitled X-Men: First Class sequel goes out July 18.

Moving to August not only gets Marvel's untitled film out of the way of the Spider-Man and Planet of the Apes sequels, it also puts more room between it and Marvel's Captain America sequel, which hits theaters April 4, 2014.

The identity of the Marvel project has been kept top secret, though sources have told THR it will be The Guardians of the Galaxy, which brings a new gang of superheroes to the big screen.

The Guardians of the Galaxy are a band of space-traveling heroes from the 31st century who were introduced into the Marvel Universe in 1969. The team has a long comics history but is relatively unknown to casual fans.
