Actor David Duchovny left a US clinic after undergoing several weeks of sex addiction therapy.
"He is out and will very soon begin work on his new movie," Duchovny's lawyer Stanton Stein told People magazine.
The 48-year-old actor, who plays an oversexed novelist on TV series Californication, successfully completed therapy, Stanton added.
In January, Duchovny won a Golden Globe for his Californication role as Hank Moody, a womanising single father struggling with writer's block.
In late August the X-Files star admitted to his addiction and went into rehab.
He has been married to actress Tea Leoni since 1997. The couple has two children, daughter Madelaine West, 9, and son Kyd, 6.
