* ButIPlayOneOnTV: She recalls in some interviews that some people call her a bitch to her face because they found Cersei Lannister so unlikeable.
* RealLife/MeanCharacterNiceActor: She's played more than her fair share of villains such as Ma-Ma and Cersei, and even her more sympathetic characters tend to lean toward uptight or anti-heroic. In reality, Lena is a fun-loving and friendly woman with a goofy sense of humor who is adored by her cast mates.
* StarMakingRole: Although her roles in ''Film/ThreeHundred'' and ''Series/TheSarahConnorChronicles'' gave her attention, ''Series/GameOfThrones'' is generally remembered as what truly made her a star.
* TypeCasting: As queens and other women trying to raise their sons to be great men. Subverted in ''Film/{{Dredd}}'' where she's called "Ma-Ma" but isn't an actual mother.
