If anyone cares here are some interviews I found of Robert Downey Jr commenting on Sheen.

He(Sheen) is a big boy. He can do whatever he likes. RDJ's practically telling Letterman
"What do you want me to say to him? huh?"
"You want ME to give him advice? he's better off on his own"
Damn straight. Yeah, he did some crazy stuff, but he's managed to phone in or appear on TV and radio every day it seems for the past week, add to that twitter in the past few days. During that time he passed a drug test. If Charlie Sheen really was hoovering up cocaine, screwing his porn star "goddesses" 24/7 and generally being out of it, I highly doubt he could have even done all that press, let alone be bothered to do so when your that high.
David Letterman was being a grade A douchebag who RDJ quickly put in place. The only reason any of this is happening [EDIT: "This" being the Chaim Levine shitstorm that started the recent furore] is because Two and A Half Men wasn't running, if everyone did go back to work when he was out of rehab none of this would have happened. Sure, his initial stint at rehab/home/thinking himself better put the show on hold, but he did turn up for work a week later and no one was there. When he asked why, Chuck Lorre told him there were no scripts. Charlie asked why, Chuck apparently gave him some BS response and that's what started this whole thing off.
Thoughout all of this, Charlie has made some valid points, namely "why wasnt there any scripts?" Now he has been extremely brash with his comments, but it is a valid question, one Chuck Lorre hasn't answered. All we got was that ridiculous vanity card about....something.
From that point of view, which I think is the one Charlie Sheen is looking at it from, the wall of silence from CBS/Lorre means he is "WINNING" this argument, because I've heard nothing from them about the cancellation of Two and a Half Men except the comments Charlie made, which have now in the sense of the story, long since past. From the moment he showed up on an empty set, there was no reason for the show to be canceled as that was long before any of this "Chaim Levine" stuff happened.
Yes I've laughed at the craziness of it all. Yes, Charlie Sheen did have an "epic party" filled with drugs and his "goddesses", but I honestly think all that stuff from a TV show production point of view is in the past now. There is no reason why CBS/Lorre and Sheen shouldn't sit down and talk about this. Sheen seems willing, and the ball is now in CBS and Chuck Lorre's court to answer some of Charlie Sheen's perfectly valid questions.
