A 21st century actress
Actresses from the early silents/talkies looked and acted as if they lived and were working in the 1920s-1930s.
To me, there are only two actresses from that era who could appear in a 21st century film and not look out of place in terms of appearance, behavior, and talent: Clara Bow and Laura La Plante. Of course, facial make-up would be much different in today's movies.
E pluribus unum
