One of the most exciting things in the trailer for Captain America: Civil War was the brief scene with Spider-Man helping Iron Man's team. I particularly like it when Tony Stark yells out "Underoos!" and Spidey flips into action taking Cap's shield. I totally had those Spider-Man Undergoes growing up. While the first time that Spidey shows up in a Marvel film will be in Civil War, Marvel has already announced the title of Spidey's first solo film under the Marvel umbrella.
