 A teaser trailer was leaked on the Internet and aired at San Diego Comic @-@ Con International in July 2011 , attached to the superhero film Captain America : The First Avenger . Rob Keyes of Screen Rant felt that " it takes on a noticeably different tone from that of Raimi trilogy of Spider @-@ Man movies , and presents itself in a similar fashion to what Christopher Nolan did with Batman Begins . " Some writers observed that the trailer very closely resembles the 2008 video game Mirror 's Edge . After the third trailer was released , Webb defended the point of view footage , saying it was an early rendering and that the CGI was still in production .
