Rachel McAdams wanted to "reassess" her career after starring in 'Mean Girls'.
The 36-year-old actress - who shot to fame after playing Regina George in the teen comedy in 2004 - has revealed she was forced to rethink what it meant to her to be successful after being propelled into the limelight with the role.
She said: "I had to kind of reassess and go, 'What did I want this [success] to be, and how did I expect it to look?'"
The pretty star - who also appeared in the 'The Notebook' opposite Ryan Gosling and 'Wedding Crashers' shortly afterwards - decided to take a two year break from acting after starring in 'The Family Stone' in 2005.
Her latest role will see her play detective Ani Bezzerides in the US series 'True Detective' and Rachel - who prefers to take on "villainous" characters - was thrilled to have been cast in a strong female part.
Speaking in the June issue of Marie Claire magazine, she said: "I love that she's not the girlfriend or the wife. She doesn't really care what everyone thinks; she feels no responsibility for other people's feelings. She's not trying to be charming, which isn't always the case with a leading lady. There's [usually] sort of a responsibility to be a little bit likeable... Not that you want to be a horrendous character, just a little more human.
"I prefer to be a villainess. There's something a bit more delicious about their wickedness."
