Sorry, Peter, I couldn't resist.
It's nice to know that Orson was in fairly good spirits and keeping his hand in, as it were, right up to the end.
Peter Ustinov used to appear on talk shows quite often a few years back, and as I recall, he didn't feel the need to push any current project. Ustinov's artful blend of serious conversation, droll observations and hilarious imitations was enough to warrant his presence in the studio.
Not to dismiss Welles' feats of prestidigitation (which were always fun to watch), but I wonder why he didn't discuss and show clips from his more personal projects (like The Dreamers) on The Tonight Show, Tomorrow with Tom Snyder, Merv Griffin, Good Morning America, etc...
