Philip Seymour Hoffman was found in his Manhattan apartment on Sunday morning after dying of an apparent heroin overdose at the age of 46. Now, reports of his longtime drug use are surfacing as the world mourns one of the most respected actors in the industry.

Hoffman never hid his struggle with addiction and spoke openly about his battle with drugs, which he fought since in his 20s. It was reported that he was in rehab last May for substance abuse. Rebecka Schumann was on hand to talk to IBTimesTV about the reports that allege the Oscar-winning actor was spending up to $10,000 a month on drugs.

Police have said that Hoffman was found on his bathroom floor and pronounced dead on the scene. According to reports, there was evidence of heroin and a needle in his arm. A full autopsy will be conducted today as police try to track down the actor’s last movements.

Now, the world will remember him by his legacy of powerful films that cemented his place in film history as a true character who loved to dive deeply into his characters as a method actor. He won an Oscar in 2005, for his portrayal of real-life crime novelist Truman Capote, in the film "Capote."

Hoffman had joined the hugely popular franchise “The Hunger Games: Catching Fire” as head game-maker, Plutarch Heavensbee.  Lionsgate, the studio that is producing the film series, released a statement describing him as “one of the most gifted actors of our generation."

The statement continued: "His character will not be replaced, nor will the release dates for both films be changed.

The people who will no doubt be affected most by the tragedy are Hoffman’s family who released a statement that said,  “We are devastated by the loss of our beloved Phil and appreciate the outpouring of love and support we have received from everyone. This is a tragic and sudden loss and we ask that you respect our privacy during this time of grieving. Please keep Phil in your thoughts and prayers.”
