The Amazing Spider-Man 2
Need I remind you what happened last time Andrew Garfield showed up at Comic-Con to talk Spider-Man? OK, I will: this. When he comes this year to promote the sequel, I'm not sure he can top that endearing moment, but I am sure he will be adorable trying. And maybe we'll get some answers about the next few Spider-Man films, particularly about his love interests, since Mary Jane's appearance has now been pushed back to the third film.
