Some may dismiss  Comic-Con International as a geekfest, but the true fans know that it’s four days of fun when they can meet industry stars and play in a fantasy land, all in downtown San Diego. 

And of course, fantasy = serious cosplay. People at Comic-Con come dressed to impress, rocking everything from comic book superhero looks to Game of Thrones realness. Here are some of our favorite costumes from this year's Comic-Con.
