Tony Clifton---the alter ego, as said, of the comic genius Andy Kaufman.The Clifton character was a creation of Kaufman's great imagination and there were 2 custom made masks made--one for him and one for his friend/mgr Bob Zmusa. You never knew which one was Clifton---then there were those that believed there was a Tony Clifton.
The sad part is that so many people thought that his period of dying was a put-on as was so much of his material. He is gone---and no more milk and cookies after the concert at his house---all those chartered buses taking people there after his Carnegie Hall gig.
A comic genius!!!
Try to read the bio by Zmusa---it really captures the comic genius of Kaufman--better than the film (which I thought was good).
