Popular recurring guest stars Ted Danson and wife Mary Steenburgen are the latest to sign on to join Jeff Garlin, Cheryl Hines, Susie Essman and series creator Larry David for the upcoming ninth season.
As the show follows an exaggerated version of David's life, Danson and Steenburgen play themselves on the show. Both actors are also currently appearing on other shows, as Danson stars with Kristen Bell in NBC's The Good Place and Steenburgen plays a lead on Fox's Last Man on Earth.
In June, HBO announced that Curb would be returning after a 5-year hiatus.
"We're thrilled that Larry has decided to do a new season of Curb and can't wait to see what he has planned," HBO programming president, Casey Bloys, said in a statement.
When asked why he chose to come back, David joked, "In the immortal words of Julius Caesar, 'I left, I did nothing, I returned.'"
While Garlin, Hines, Essman, Danson and Steenburgen have been with the comedy from the beginning, later seasons saw J.B Smoove's character, Leon, become an integral part of the series as well.
In a radio interview with Rich Eisen earlier this year, Smoove expressed an interest in doing more episodes.
"I'll move anything I'm doing to the side for Curb Your Enthusiasm, which would be a fabulous thing to do," he said. "Season nine would be fabulous."
With 80 episodes to date, the Golden Globe-winning series is HBO's longest-running scripted comedy or drama.
