The actors promoting their latest films and television series aren't the only stars of Comic-Con International - the thousands of fans who don elaborate costumes for the convention help to boost its unique atmosphere.

The four-day extravaganza provides some amazing mash-ups of pop culture - zombies mingling with superheroes from various comics and plenty of other custom creations.

An estimated 130,000 people descend on the San Diego Convention Centre for Comic-Con, which features panels on everything from comic books to Hollywood blockbusters.
