Stone voiced an Australian Shepherd in "Marmaduke" (2010), a comedy from director Tom Dey, which is based on Brad Anderson's long-running comic strip of the same name. Her breakthrough came the same year with a starring role in "Easy A", a teen comedy directed by Will Gluck. Partially based on Nathaniel Hawthorne's 1850 historical romance novel "The Scarlet Letter", the film tells the story of Olive Penderghast (Stone), a high school student who becomes embroiled in a comic sex scandal after a false rumor circulates that she is sexually promiscuous. Stone read the script before the project was optioned for production, and pursued it with her manager while production details were being finalized. She found the script "so different and unique from anything I'd read before", saying that it was "funny and sweet". When Stone discovered that the film had begun production, she met with Gluck, expressing her enthusiasm for the project. A few months later, the audition process started and she met again with Gluck, becoming one of the first actresses to audition. The film received positive critical reviews, and Stone's performance was considered its prime asset. Anna Smith of "Time Out" wrote, "Stone gives a terrific performance, her knowing drawl implying intellect and indifference with underlying warmth." The film was a commercial success, grossing $75 million against its $8 million budget. Stone was nominated for a BAFTA Rising Star Award and a Golden Globe Award for Best Actress in a Musical or Comedy, and won the MTV Movie Award for Best Comedic Performance.</ref>
