I just saw Robert Vaughn in a special about Steve McQueen. I think it was on the AMC channel. Maybe TCM. I'm not certain how long ago this special was made, but I can say that Robert Vaughn looked darn good. Vaughn had co-starred with McQueen in "Bullit". A great movie!
My favorite role of Vaughn's was his one-man portrayal of Franklin Roosevelt. I think it was done some 20 or so years ago when one-person dramas seemed so popular (Give'm Hell, Harry and Belle of Amherst). I think it was on Broadway for a while and then made into a TV special.
