This year, Wizard World Chicago Comic Con assembled one of its best celebrity guest lineups to date, welcoming actors like Carrie Fisher, Michael J. Fox and David Duchovny. But, as usual, the highlight of the comic book convention was the creation costumes that attendees showed off on the floor—it almost felt like Halloween had arrived early. We spotted Kylo Ren, Harley Quinn and even Earthworm Jim. Take a look at some of the event's best cosplayers in our gallery of photos from Wizard World.
