We all met her when she was eleven years old and portraying the one and only Hermione Granger in Harry Potter and the Philosopher's Stone. Emma Watson then went on to play the same character in the remaining seven Harry Potter films, which set her career up in a big way. Though she made more than enough money from the Harry Potter franchise, Watson continued to star in blockbuster films, cementing her career as a serious actress.
Most actors who are known for playing one character can fall into the trap of never working outside of that role again - but not Watson. Since Harry Potter, she has starred in My Week with Marilyn, The Perks of Being a Wallflower, The Bling Ring, Noah, Beauty and the Beast, Regression, Colonia, and The Circle. She's also a feminist activist with the United Nations.
