I also have the idea for the whole trilogy of films. First off, if Marvel wants to make a new franchise with this film and believe me they do, the first one MUST be set in WWII! My script is and he falls into the arctic ocean at the end and SHEILD finds him present day which leads into part two which is the whole man out of time thing, which is a brilliant theme, but don't rush it! Then the second one deals with Cap in modern day, asking himself what has America become? What is this military machine that now controls the world? And do I want to help it? Of course he does when Hydra comes out of nowhere as an elite terrorist group. then hes got his shiny new costume. His introduction to the public, and his romance with Sharon Carter. Then for the third you go vry DARK. Like spider-man, you set up certain people in the govt being traitors in the second and they try to take over the US in the third. Plus you bring the winter soldier storyline in their too, tweak it a lil bit of course, and at the end you have your iconic CAptain America bringing the US back to what it once was and what it once stood for. Voila! Theres your trilogy. After that bring in the Avengers, but give Cap his own trilogy he deserves it.
