What more can be said about the "Blonde Bombshell" that hasn’t been said before? Born Norma Jeane Mortenson, Marilyn Monroe is definitively one of America’s most famous pop icons. There’s a good reason why legendary pop artist Andy Warhol decided to immortalize her with a series of paintings: Marilyn not only perfectly encapsulates Hollywood in the '50s but also serves as a great representation of how the world sees the American dream.

Monroe’s first on-screen appearance dates back to 1947, when she briefly appeared as a waitress. Nobody knew that this small role would be followed by an extremely profitable career, which included classics like Some Like It Hot , The Seven Year Itch , and The Misfits .

Many of the actresses on this list are considered Hollywood royalty, but only Grace Kelly holds the honor of being an actual princess. However, while her marriage to Prince Rainier III of Monaco was truly a spectacular moment, we shouldn’t overlook the incredible career of this amazingly talented actress.

After a number of small roles, Kelly first achieved stardom with her performance in John Ford's 1953 film Mogambo , for which she was nominated for her first Academy Award. That being said, perhaps her most iconic roles are the numerous Hitchcock films she appeared in, including such classics as Dial M for Murder , Rear Window , and To Catch a Thief .

Sometimes actresses and actors are typecast after a particularly amazing role: Carrie Fisher will always be Princess Leia, Anthony Hopkins will always be Hannibal Lecter, and Judy Garland will always be remembered as the brave Dorothy Gale from The Wizard of Oz . And while this role truly cemented Garland as an undisputed American icon, there’s so much more to this amazing actress's career.

Garland’s incredible voice and acting chops skyrocketed her to fame from an early age. One year before portraying Dorothy, she starred alongside Mickey Rooney in the 1938 film Love Finds Andy Hardy . As an adult, she received Oscar nominations for such iconic films as A Star Is Born and Judgment at Nuremberg .

Regardless, this amazing American actress is still remembered as one of Hollywood’s most iconic legends.

Elizabeth Taylor’s many acting roles are too many to count, so we’ll leave you with a few of our favorites: two film adaptations of Tennessee Williams’ plays, Cat on a Hot Tin Roof and Suddenly, Last Summer , and her performance as the Queen of the Nile herself in the 1961 film Cleopatra .

It should go without saying that all the actresses on this list have multiple talents, including singing and dancing.

Born in Independence, Missouri, but raised in Kansas City, Rogers began her career in a vaudeville act at the age of 14. In the 1930s, she met her perfect partner in crime, Fred Astaire. From 1933 to 1939, the duo starred in 9 iconic films, which completely revolutionized the Hollywood musical genre.
