HST > Notable? 

832, In the heading it says: "Notable roles". The three previous mentions were roles that the play and/or film, Truman was the main subject, taking up the bulk of screen/stage time and lines. These also won critical acclaim. The combination of the amount of script and praise is what made these portrayals of Truman notable. Does your addition really fit: "Notable"? There have been lots of roles with Truman in them:

The Man from Independence (1974) Played by Robert Vaughn (as Harry S Truman)
The Beginning or the End (1947) Played by Art Baker (as President Harry S. Truman)

But, Give 'em Hell, Harry! and Truman, both on stage and screen where entirely about Truman. In Give 'em Hell (if you have seen it), there is nobody else. It is a one-man play, 100% of the lines are portraying Truman. And Flanders played Truman at least four times, including the bulk of the work being about him in at least two occasions; Harry S. Truman: Plain Speaking and Truman at Potsdam. So, is his charactership in Flags of Our Fathers really "notable"?
