HBO CEO Richard Plepler has confirmed that Curb Your Enthusiasm Season 9 is still in the mix, per TV Insider:
When will we finally see the return of Larry David’s Curb Your Enthusiasm or [Sopranoscreator] David Chase’s next project?
Plepler: David is writing and researching and doing what he does, methodically understanding the time period. He gave us a script to his miniseries, which was fantastic. And Larry knows that when he’s ready, we’re ready.
