Jason Momoa has been announced as one of the featured celebrity guests for this year’s Wizard World Comic Con in St. Louis. Momoa is best known for his portrayal of Aquaman in the DC blockbuster of the same name, though Game of Thrones fans would certainly know him better as Khal Drogo.

The expo will be held at America’s Center on April 5, 6, and 7. Momoa is scheduled to make his appearance on Saturday, April 6.

Admission to the event starts at $39.99 for Friday, $54.99 for Saturday, and $49.99 for Sunday. Three-day admission passes are $79.99. Fans can purchase photo and/or autograph packages for the world's most famous fish-talker and other stars for an additional fee.

Additional guests include Sean Astin (Lord of the Rings), Chris Kattan (Saturday Night Live), Daniel Cudmore (X-Men, Twilight), and three stars of the show Charmed (Holly Marie Combs, Brian Krause, and Drew Fuller). More guests will be announced in the days and weeks to come.
