Pretty even I think. Morrison was a good looking guy, no doubt, but so was Val Kilmer. Too close to call.
John F Kennedy was better looking than both Greg Kinnear and Martin Sheen. Richard Nixon was better looking than Rip Torn, Anthony Hopkins and Frank Langella.
If you're going to go there, you might even say that Lincoln was better looking than Raymond Massey...
Babe Ruth > John Goodman Fred Flintstone > John Goodman Brian Piccolo > James Caan Alex Karras = Alex Karras
This example is the perfect time to be reminded, an icon takes an entire lifetime to age; the actor playing him gets three years of growth and body maturation, tops. And, maybe a wig change or two.
Eve Plumb is extremely more attractive than the person who portrayed her in the Brady Bunch movies...or for that matter, replaced her when she didn't do various Brady Bunch projects after the series.
Kurt Russell was surprisingly good as Elvis back in the 1979 TV movie. He has said many times how grateful he was to director John Carpenter for casting him in this film and reviving his career.
That photograph is of Massey in the role of the killer, Jonathan Brewster, in 'Arsenic and Old Lace'. (Massey has lots of makeup on in the photograph.) Boris Karloff played the role on Broadway and there's a line in the play which they kept for the movie about Brewster looking like Karloff (or Frankenstein).
Dorothy Stratten was quite a bit more attractive than the actress Mariel Hemingway who portrayed her in Star 80.
Hemingway was an odd choice because she's considerably less top-heavy than Stratten. Never saw the movie so I don't know how well Hemingway did in the role, but physically, she was a poor match for Stratten...
