“Curb Your Enthusiasm” — still beloved and still off the air, at least in originals, after five years — will return for a ninth season, HBO announced Tuesday.

No details about timing, but in a statement, Larry David, star and showrunner, said this: “In the immortal words of Julius Caesar, ‘I left, I did nothing, I returned.’ ”

Casey Bloys — named president of HBO programming earlier this month — said in a statement: “We’re thrilled that Larry has decided to do a new season of ‘Curb’ and can’t wait to see what he has planned.”

“Curb” left the air in 2011, and the guessing game has continued ever since: Will David do another season? Does he want to do another season? Does he have the material for another season?

Moreover, co-stars, colleagues and even friends (yes, LD has plenty of friends), have guessed as well. But no one really knew, until now.

“Curb” — a work of comic genius, for the most part — followed David’s exploits as a financially comfortable former creator/showrunner and co-creator of one of the most successful comedies in TV history, “Seinfeld.” Was he happy in these prosperous circumstances? Never, except when he was unhappy, which was pretty much all the time.

With 80 episodes to date, the show is HBO’s longest-running scripted comedy or drama series.
