San Diego Comic Con: New 'Spider-Man' Makes Surprise Appearance

July 23, 2011— -- Fans of Spider-Man got a sneak peek of the upcoming film reboot of the series at San Diego's Comic Con this week.

Andrew Garfield, dressed in a Spider-Man costume, surprised the crowd Friday as the film's new Peter Parker at the beginning of the film's panel discussion at the festival.

"The Amazing Spider-Man" is the fourth recent Spider-Man movie, after three major film successes directed by Sam Raimi and featured Tobey Maguire as the Spider-Man.

Garfield was tapped to play the webslinger in a franchise reboot directed by "500 Days of Summer" director Marc Webb.

While it was hard for the crew to replace Raimi and Maguire, but they were gracious.

"We all feel humble and honored to take on this mantle in some way," said Webb.

Also starring in the new movie are Emma Stone as love interest Gwen Stacy, Sally Field as Peter's Aunt May and Martin Sheen as Peter's Uncle Ben.

Scenes from the film were also shown at the panel discussion including a video of the villain, the Lizard.

The Lizard is a scientist turns into a monster after attempting to grow back a missing limb by using a piece of reptile DNA.

The choice of the villain in comic book movies, like this one, are ripe for fan approval or disapproval.

One of the criticisms of the third Spider-Man movie was that it simply had too many bad guys.

Webb said he took his inspiration for his the movie's nemesis from his movie's heroes.

"I think to me it emerged from the thematic part of the movie we're trying to make. Peter Parker has missing pieces, we all have missing pieces. It's how we look to fill that void that defines us," Webb said in an itnerview with ABC News.
