Philip Seymour Hoffman found dead at 46

Academy Award-winning actor Philip Seymour Hoffman was found dead in his New York City apartment on Sunday. He was 46 years old.

Investigators discovered a syringe in his left forearm, and though the exact cause of death is yet to be determined, police officials believe he succumbed to a drug overdose.

Hoffman had checked into rehab in May of 2013 for heroin use, citing a relapse in his 23 years of sobriety.

He leaves behind his wife of fifteen years, Mimi O’Donnell, and three children under the age of 10, Cooper, Tallulah, and Willa.

After establishing himself as one of America’s most essential supporting character actors, he won the Best Actor Oscar in 2005 for the biopic Capote. 

He earned three further Oscar nominations for Best Supporting Actor, thanks to his turns in Charlie Wilson’s War, Doubt, and The Master. The stage veteran also had three career Tony nominations.

The late actor stars in three films due for release in 2014: John le Carre adaptation A Most Wanted Man, indie flick God’s Pocket, and The Hunger Games: Mockingjay – Part 1.

He did not complete filming his part in Mockingjay‘s second instalment, due out in 2015.

A new television program from Showtime, titlted Happyish, featured him in the lead role, though only the pilot was completed.
