Actor Justin Theroux, 44, is in a bit of hot water following allegations from an extra on the set of HBO's "The Leftovers" that Theroux made a distasteful joke about New Yorkers and 9/11. But the controversy may just be a bit of hot air. The actor denies that he ever made any such joke and claims he never would. 

On Sunday, the New York Post's Page Six reported that Theroux had joked that the Sept. 11, 2001, attack was good for New Yorkers as it led to reduced rent prices downtown. The allegations came from an extra on the set of "The Leftovers," the cerebral HBO series on which Theroux is the star. The extra, who remained anonymous in the story, quoted the actor as saying, “9/11 was the best thing that happened to New Yorkers."

A representative for Theroux was quick to issue a response. 

"As a New Yorker and someone who has lived downtown for over 20 years, Justin would not make jest of 9/11," said the actor's rep, according to US Weekly

Theroux is a long time New Yorker who has performed in various stage productions in the city. He purchased a luxurious Greenwich Village apartment shortly after 9/11, fresh off of starring roles in David Lynch's "Mulholland Drive" and the 2000 "Charlie's Angels" reboot, that was profiled by the New York Times in 2003. Theroux married actress Jennifer Aniston, 46, in August, according to People

As for Theroux's show. Season 2 of "The Leftovers," which has been met with near universal acclaim, is gearing up for its big finale Sunday. According to the synopsis for the episode, Kevin (Theroux) confesses his possible involvement in Evie's (Jasmin Savoy Brown) disappearance to her always-agitated father, John (Kevin Carroll). It is not like he has much of a choice, though. Fans will remember that in episode 7, a desperate Kevin showed up at the fire station looking for help getting out of Nora's (Carrie Coon) handcuffs and ended up being pressured into submitting to John's town-wide fingerprint registry. After that, it was only a matter of time before John discovered that Kevin's prints and the ones found on Evie's car are a match. However, episode 9's reveal that rogue Guilty Remnant leader Meg Abbott (Liv Tyler) has Evie would seem to, at least partly, absolve Kevin of any wrongdoing. Either way, the stage is set for an exciting end to the season.

Will Theroux face any blowback for his alleged joke? Only time will tell. "The Leftovers" airs Sundays at 9 p.m. EST on HBO.
