Costumed fans dressed as superheroes and villains are descending on San Diego for the 45th annual Comic-Con.

More than 150,000 fans are expected to attend the four-day festival celebrating film, TV, video games, comic books and costumes.

After more than four decades of Comic-Con, the festival has outgrown the San Diego Convention Centre and spills out on to neighbouring streets and hotels.

Wonder Women, Batmen, Klingons and the undead mill about the streets of the city. IBTimesUK takes a look at some of the attendees at this year's event.
