If you're splitting hairs here's Vesper's description of Bond from the Casino Royale book:
"reminds me rather of Hoagy Carmichael, but there is something cold and ruthless."
and in Moonraker, Gala Brand notes:
"certainly good-looking . . . Rather like Hoagy Carmichael in a way. That black hair falling down over the right eyebrow. Much the same bones. But there was something a bit cruel in the mouth, and the eyes were cold."
Dalton was the closest to the Hoagy Carmichael ideal Fleming envisioned, IMO.
Here's a pic Ian Fleming commissioned to give readers an idea as to what he imagined his Bond to look like:
Looks like a less craggy Dalton to me.
Don't get me wrong, I love DC but he look more Boris Becker than James Bond. He really should have dyed the hair.
