I hate how we canonize everyone who dies, it sort of cheapens it when I say Philip Seymour Hoffman was absolutely the best of the best.

R.I.P. Philip Seymour Hoffman. One of the greats of his generation.

The Oscar-winner had been sober for 23 years before suffering a relapse in 2012.

Hoffman was born July 23, 1967, and was nominated for four Oscars and three Tonys.

He leaves behind three children, ages 10, 7 and 5.
