C2E2: Chicago Comic and Entertainment Expo
Time Out says
Each year, C2E2 brings a ton of comic book creators and some notable TV and movie stars to McCormick Place for a bonafide pop-culture bonanza. Head to the convention floor and you'll find cosplayers, attendees and creators mingling in a sea of vendors hawking all manner of comics, toys and memorabilia. You can also line up to attend a panel or score an autograph from some of the notable guests in attendance, including Paul Rudd (who will reunite with Clueless co-stars Alicia Silverstone, Donald Faison and Breckin Meyer), video game voice actor Nolan North and Firefly actress Summer Glau.
