The Marvel Cinematic Universe is an ever growing one. With that in mind, here is a guide to the Marvel Studios series films:

1.
Iron Man (2008)
Billionaire weapons manufacturer Tony Stark finds himself at odds with both his death dealing enterprise and his debaucherous, alienating lifestyle. He is forced to make life changing, and saving, decisions that throw him into the new identity of Iron Man.
The film both marked the emergence of Marvel Studios and
Robert Downey Jr.'s launch into stardom with a new generation of movie goers. It showed that Marvel was taking control of its film endeavors, no longer relying on outside studios to bring characters to the screen, and also hinted at more to come.

2.
The Incredible Hulk (2008)
Dr. Bruce Banner transforms himself, by way of a gamma radiation experiment, into a hulking green monster. Triggered into the uncontrollable hulking form by anger and stressful situations, Banner flees the country while the US Army tries to both control and replicate the results of Dr. Banner's experiment.
Following the huge success of
Iron Man, the film offered both an expansion to the Marvel movie universe as well as a welcome replacement to
Hulk from 2003.
Edward Norton delivered a compelling performance, and director
Louis Leterrier did a better job than previous efforts at balancing the Hulk's potential to be more of a monster movie than a superhero flick, although some still were disappointed at the films efforts. A cameo by Robert Downey Jr. as Tony Stark solidified the new films' shared continuity.
