Sarah Michelle Gellar
Who: Sarah Michelle Gellar
Why she was here: It's hard to believe, but the "Buffy" icon had only been to Comic-Con once before to promote "The Grudge. " This year, she was back to hype her new series "The Ringer" and received a standing ovation from a packed Ballroom 20. She may not be at her early 00's heights in most of America, but at the con she's still a superstar.
