“There is no me.
I do not exist.
There used to be a me
but I had it surgically removed.”
Naturally he is only joking in this quote; however, there is an element of truth in it -Like many actors he did actually feel as if he didn't quite know who he was outside the personas of the fictional characters he created. He was one-off, unique. So it seems odd to us that he should have felt that he did not really exist as an individual, in a sense. Uniqueness is a quality bestowed by the Self, not by the banal ego.
