Philip Seymour Hoffman's problems with addiction

In the original interview, Hoffman tells Kroft he was fresh out of New York University's drama school when he was lured into New York City's fast life. "It was all that [drugs and alcohol], yeah, it was anything I could get my hands on...I liked it all," he said.

 But he saw the need to change early. "I went [to rehab], I got sober when I was 22 years old," said the-then-38-year-old Oscar nominee.  "You get panicked...and I got panicked for my life," says Hoffman. "It really was just that."

He won the Oscar for best actor that year for his portrayal of Truman Capote.

 He also realized that getting sober before he got famous was a blessing.  "I have so much empathy for these young actors that are 19 and all of a sudden they're beautiful and famous and rich," Hoffman says.  "I'm like, 'Oh my God. I'd be dead.' You know what I mean? I'd be 19, beautiful, famous and rich. That would be it," he told Kroft.  "I think back at that time. I think if I had the money, that kind of money and stuff.  So, yeah [I would have died]."

Hoffman, 46, was found dead Sunday in his New York apartment, where authorities found packets heroin and a syringe.
