-- John Stamos is stepping into totally new territory.
The actor will guest star in the upcoming ABC musical comedy series, "Galavant," about a hero living among corrupt royals, noble knights and more.
“We are absolutely thrilled that John Stamos is joining us on the series as Galavant’s longtime rival -- a dashing knight who squares off against him once more in a local joust," executive producer Dan Fogelman told ABC News in a statement. "We’ve wanted John to do an arc on this show since inception."
Stamos, 50, will begin filming next month in Bristol, England. While he'll definitely be in at least one episode, there is a chance he will return for more as the show goes on. Fogelman would certainly welcome the opportunity to work with the "Full House" veteran as long as possible.
"He's funny as hell, and he sings, and he looks like Lancelot wishes he looked," he said. "We can’t wait!"
