We’ve known for years that Castle’s  Nathan Fillion is a Geek Greek God, but the sexy stud is about to make it official in the Percy Jackson sequel titled Sea of Monsters. The popular mythology book series’ second installment is set to be a summer blockbuster, as it hits theaters on August 16.

But to help ease the pain of waiting, TV Guide has just released the first look at Nathan in the role of Hermes. And like Richard Castle, it seems this god is going to have more than a touch of humor.

"I'm a god, father to one of the young demigods [half-blood Luke]," Nathan said. "I'm not allowed contact with humans as a god, so I dress as a UPS guy."

Hermes is the messenger god ... get it?

In the sneak peek image, Nathan has on his suit and tie (Justin Timberlake-style) with his hair slicked back. And is it just us, or is he glowing like the otherworldly character he’s playing? Swoon.

We can’t wait to see this studly actor looking sharp for the Percy Jackson sequel. What about you? Will you go see the film in August? Tell us below!
