Robin Williams was a brilliant comedian and a great actor. His comedy came across as a total stream of consciousness thing, as if he had done too much blow and everything just came spilling out of him. And it was only later on that I learned that he was Julliard trained. His work with Jonathan Winters was beyond brilliant.
It seems that some of these guys who are so filled with joy and brilliance are also filled with equal amounts of darkness. And it seems really sad that his peaks and valleys were so extreme. Rest in peace.
