We should be getting our first official look at Captain America: Civil War fairly soon, but in the meantime here's an interesting bit of Spidey info. from Heroic Hollywood. According to the site, Peter Parker will have been active as Spider-Man for a little over a year when we first meet him in the Marvel threequel, and, like the Ben Affleck's incarnation of the Dark Knight in Batman V Superman: Dawn Of Justice, "Spider-Man is considered a myth, an urban legend."
Apparently by the time we catch up with Peter in the standalone Spider-Man flick, he'll have been doing his thing for two full years.
Not much, but it's good to know we won't have to sit through another damn training montage anyway!
