What was the purpose of this wonderful clip of Don Rickles roasting Clint Eastwood on the set of ‘Kelly’s Heroes’? Was it for TV? For the wrap party perhaps? (I prefer to think the latter). Rickles actually makes Clint double over with laughter at one point–something never previously seen before, so far as I know. Even the director Brian Hutton gets his ass kicked by Rickles. Is the laughter from off-camera coming from the set? Or from some sort of TV audience viewing the clip? The whole thing’s a mystery. But a very funny one and, as said, a one-of-a-kind glimpse of a very different Clint from the one we all know.
