Jason Momoa is entering a new realm: Springfield.

The Game of Thrones alum and Aquaman star will get animated and guest-star in an upcoming episode of The Simpsons. Jason Momoa will assume the role of… Jason Momoa, who appears at the San Castellaneta festival (a wink to Homer voice actor Dan Castellaneta), EW has learned. “He is the celebrity that shows up and talks about this legend of this saint who was ground up and martyred and became the origin of modern-day pistachio ice cream,” says Simpsons executive producer Al Jean. “He tells this very gruesome story — and then Patty and Selma want him to sign their boobs and he runs away.”
