Philip Seymour Hoffman is considered one of the greatest actors of his generation, a fact that is sadly confirmed by the outpouring of responses from his peers and admirers in the entertainment community in the wake of his death. After the news broke, they took (where else?) to Twitter to express their thoughts, which range from denial to sadness, and, of source, sympathy to problems with addiction.

It is as clear as it ever was that Hoffman's work had a profound and lasting effect.
