That's what Robert Duvall called Joaquin Phoenix, when I moderated a panel with the actor at Cannes two years ago, just before the premiere of their film, We Own The Night. Duvall's as straight a shooter as they come, and you know he wouldn't say it if it wasn't worth saying. The actor may have come off as dazed and confused during his recent Letterman appearance, but as Steve Korn mentions over at EW, wasn't he always a bit... aloof?
P.S. All this media attention on Phoenix (whether it's a hoax or not) is good news for Magnolia Pictures and director James Gray. Let's not forget the whole reason Phoenix is in the spotlight: their new film, Two Lovers.
