Just take a long look at Rita Hayworth. She is as Hollywood as Hollywood can get. In the 1940s she was one of the biggest film stars, and throughout her 37 year long career, she was in over 61 movies. Her most famous role is in the film Gilda in which she plays the titular role.
She has that specific 40s era Hollywood look. It is almost as if Hollywood grew her in a lab, specifically designed for the movie screen. It is interesting to see how the stars change in different eras. Look at women in film from the 80s compared to women in film today. Things have changed a lot. Sometimes this leads to older movies feeling dated, but by looking at them as time capsules, it can be a good look into how things were at the time.
