Gillian Anderson – The X Files
Incredibly, The X Files star Gillian Anderson once vowed that she would never work in television. Thankfully, Anderson broke her vow and went on to become Dana Scully, FBI agent. At only 24 years old, Anderson auditioned for the role, feeling inspired at the “strong, independent, intelligent” lead character.

Since then, Gillian Anderson played DSU Stella Gibson in BBC crime drama The Fall, and starred as therapist Jean Milburn on a popular Netflix teen comedy. She has an Emmy, and a Golden Globe Award.
