Matt Zoller Seitz is a former Dallas Observer writer, Dallasite, and Wilson brothers fan. He writes a very moving article about Owen Wilson here, entitled, "A Sunbeam in the Abyss." Here's a little from the piece:
Art is always informed by life, but one doesn't automatically predict the other. Depression is an implacably private thing, a fog comprised of biography, present-tense experience and body chemistry. It's as unpredictable as the elements and as unknowable as God. It's an abyss that you fall into, and you either die there or climb out.
Owen, peace be with you.
