Yes, and a true story.Hank, I don't believe that I have. Was it good?
DeNiro played the role of a man who was in a vegetative state.
Robin Williams played the doctor who worked at the institution where he lived.
He used a drug called L-Dopa, it "awakened" him and he was normal for a while but the drug became more and more ineffective and DeNiro slipped back into oblivion.
Not that Carly is vegetative - anything but that.
However your phrase "pushed back into oblivion" made me think of the character DeNiro played.
