Первый мститель
The film was promoted at the 2010 San Diego Comic-Con International, during which a teaser trailer narrated by Samuel L. Jackson was shown followed by an introduction of the cast. In June 2011, Marvel Studios announced that it would not hold a panel at the 2011 San Diego Comic-Con International after studio executives decided it was not prepared to compete with its own past and fan expectations with filming still in production. In July 2011, a teaser trailer that was meant to be the post-credits scene of "Captain America: The First Avenger" was briefly leaked online. "Entertainment Weekly" speculated it came from a preview screening and described the footage as "shaky, fuzzy, flickering and obviously filmed on a cell phone".
