Christopher Plummer
Many would agree that Christopher Plummer was most famous for playing Captain Georg Von Trapp in The Sound of Music (1965) alongside Julie Andrews. He absolutely had the serious and dignified looks befitting the role of the Navy officer and Trapp family patriarch. And the Canadian actor looked absolutely dashing in those suits.
Christopher Plummer had the looks and dignified aura to play multiple historical figures, members of royalty, and other dramatic roles. Of course, you can’t really avoid time messing with appearances, thinning hair, coloring it white, and drawing wrinkles. Despite that, though, Christopher Plummer carried those marks of age quite well.
