Two days ago the Hollywood Reporter's Lindsay Powers reported that David Letterman was in on the Joaquin Phoenix meltdown joke all along. She quotes Late Night staff writer Bill Scheft as follows: "Dave knew about it and Dave loved it because he could play along. It was great television. I've told people that [everyone was in on the joke], and not only don't people believe me, they tell me that I'm wrong and that [Phoenix] is a schizophrenic and he needs help and he's going to end up like his brother [River, who died of a drug overdose in 1993]. I said no. I saw the segment notes. It's an act. I saw Ben Affleck's brother taping the whole thing from offstage."
