LOS ANGELES -- 'X-Files' star David Duchovny has completed rehabilitation treatment for sex addiction and is preparing for work on a new film, the actor's lawyer told People magazine Tuesday.

Duchovny, who has re-launched his career in recent years by playing a womanizing writer in the television series "Californication", voluntarily entered a treatment program in August.

"David is out of rehab and about to start a new movie. He successfully completed his treatment," Duchovny's lawyer Stanton Stein told People.

Duchovny, 48, has been married to actress Tea Leoni since 1997. The couple have two children.

According to entertainment industry press, Duchovny is due to star in "The Joneses" alongside Demi Moore, a comedy about a fake family put together by a marketing company as a way of introducing luxury goods to their neighborhood.
