I say that Ava Gardner's name is one of the best. When I think of her first name especially, I think of peace and anything that associates with beauty like gracefulness.
Some other ones I like are:
Rita Hayworth
Barbara Stanwyck
Joan Crawford
Frank Sinatra
Laurence Olivier
Charles Boyer (French actor, so the end part is silent)
I think that many, many names are very nice sounding. With some, not so good, but basically all star's names back then had class and distinction.
