In a tweet sent Tuesday, the streaming network described the new show as "an adult animated series about aliens from a better world who must take refuge in middle America," and said it would debut in 2020.
According to Deadline, Roiland will also lead the voice cast, playing characters named Terry and Korvo. Other characters will be played by Sean Giambrone, who voiced Jeff on the animated show Clarence, and Mary Mack, who's done voice work on Aqua Teen Hunger Force and Golan the Insatiable. A report from Variety says Hulu has agreed to two seasons.
McMahan corrected fans who were confused about the new show, perhaps assuming it was coming from Roiland and the other Rick and Morty co-creator, Dan Harmon.
"Guys- this is not about THE Rick & Morty duo," McMahan wrote in a tweet. "It's a NEW duo. Who knows how many duos are hiding at Rick & Morty???"
