Most iconic actors of every generation

I will be mentioning the actors, who I personally think best define every single generation, from the Greatest Generation - Generation Z. you can include your own list.

Greatest Generation (1901-1927)

Charlie Chaplin, Judy Garland, James Stewart, & Bette Davis

Silent Generation (1928 - 1945)

Marilyn Monroe, Gene Kelly, Paul Newman & Sean Connery

Baby Boomer Generation (1946 - 1964)

Al Pacino, Robert De Niro, Harrison Ford & Sigourney Weaver

Generation X (1965 - 1980)

Arnold Schwarzenegger, Tom Hanks, Jennifer Aniston & Will Smith

Millennium Generation (1981 - 1996)

Leonardo DiCaprio, Emma Watson, Matt Damon & Jennifer Lawrence

Generation Z (1997 - 2012?)

Zendaya, Jenna Ortega, Millie Bobby Brown & Tom Holland

Are you referring to when the actor/actress was born, or which were the most defining of each generation? I think you've "mixed and matched" a few there.. For example Judy Garland was born in the Greatest Generation, but she most defined the Silent Generation, and definitely spilled over into the Baby Boomer Generation.
