Then you have the absolute greats, such as Meryl Streep, Cate Blanchett, and Helen Mirren—who all will go down as the greatest actresses of all time. Of course, we can’t forget the stars of the 2010s, including Emma Stone and Margot Robbie among many others. They’re certainly some of the most popular actresses. Acting is a highly competitive field and requires that actresses compete for roles through an audition process. Auditions are usually held with the casting director, director and/or producer. Auditions may require the actress to memorize lines or spend time researching ways to interpret the character.
