Wizard World has announced a few of the guests for this years convention. Some of the names added are Sean Astin from Goonies and Lord of the Rings, Holly Marie Combs Brian Krause and Drew Fuller from the OG Charmed, Chris Kattan from SNL and Daniel Cudmore from X-Men and Twilight. The biggest name by far is Jason Momoa! Yep Aquaman himself. Autograph and photos aren't cheap for him either! You're looking at $150 for a pic with him or 125 for just an autograph. Yipes!
