The crowds at San Diego Comic-Con, with more than 100,000 attendees, represent only a portion of those who would attend if they could: tickets were sold out in an hour or two in 2012, and within minutes in 2013.
Founded in 1970, San Diego Comic-Con has since exploded into an astounding pop culture festival, attracting more than 130,000 visitors and the attention of Hollywood studios, publishers and retailers alike, all eager to cater to their most dedicated fans.
"Comic-Con is an incredibly fantastic melting pot and passionate center for people who love cult pop movies and pop culture experience," Hobbit and Lord of the Rings star Andy Serkis told Reuters. "There isn't another place in the world that tops it."

The vast event was too much for some, even on the first day.
