During the Credits
Old school images of WWII propaganda to support the U.S. (including posters like James Montogomery Flagg’s Uncle Sam “I want you!” and “We can do it!” by J. Howard Miller) are shown during the first two and a half minutes of the credits of Captain America: The First Avenger. At the very end of the credits, in the fashion of the James Bond movies, there is a line stating that “Captain America will return in The Avengers.”
After the Credits
There is an extra scene (directed by Joss Whedon, who will direct The Avengers) and trailer for The Avengers after the credits of Captain America: The First Avenger; check out more details and spoilers below.
