Wow. Oscar winner Philip Seymour Hoffman, 45, told TMZ he checked himself into a detox facility on the East Coast for 10 days of treatment to help him battle a drug problem.

Hoffman — who plays Plutarch Heavensbee in The Hunger Games: Catching Fire, which opens later this year — told TMZ he started down this path about a year ago, after leaving his substance abuse problems behind him for 23 years. It began with prescription drugs and recently escalated to (yikes) snorting heroin.

The Capote actor, who was nominated for another Oscar earlier this year for The Master, said he only did the heroin for about a week before he realized he needed help. He checked out of rehab last Friday. He's now filming a movie in Europe. According to his IMDb, Catching Fire and A Most Wanted Man are both in post-production, and his new film God's Pocket is in pre-production.

It's shocking to hear of this drug escalation — especially the heroin — but Hoffman credited his friends and family for pushing him to seek help. He has three children with his longtime girlfriend, costume designer Mimi O'Donnell. Hopefully that 10-day treatment was all he needed, but heroin is notoriously hard to fight. If he still needs help, we hope he knows when to go back and how long he needs to recover. Good luck, man.
