At the annual Comic-Con International expo, pop-culture fandom is elevated to veritable religious status, and the convention's 130,000-odd attendees have countless ways to worship at the altars of their choosing.

Want to dress up as a Stormtrooper? Suit yourself. Want to buy a bobblehead doll of your favorite movie character? Go for it. Want to stand in line for hours for the chance to be in the same room as the stars of your most cherished TV series? Right this way. Want to stand outside the San Diego Convention Center holding a sign that says "Kneel Before Zod"? Knock yourself out.
