Wizard World Cleveland

Jason Momoa, of Aquaman and HBO's Game of Thrones, is the big star who'll be at this year's Wizard World Cleveland. The convention starts today, but Momoa will appear tomorrow at the event that takes place today, tomorrow and Sunday at the Huntington Convention Center. It's the third annual festival of pop culture, gaming, sci-fi, comics and cosplay. Momoa joins a line-up of celebs that includes Thomas Ian Nicholas (Rookie of the Year, American Pie), Sean Astin (Lord of the Rings, The Goonies), Tom Welling (Smallville) and cast members from Charmed. Tickets are $80 for the full weekend or $40 to $55 for single-day passes. There are specialty ticket packages for autographs and photo ops with Momoa himself, but these are much more expensive. A "Gold VIP Package," for example, will set you back $429.99. Children under 10 are free if accompanied by a paid adult. (Sam Allard)
