Easy A (stylized as easy A) is a 2010 American teen romantic comedy film directed by Will Gluck, written by Bert V. Royal, starring Emma Stone, Penn Badgley, Amanda Bynes, Thomas Haden Church, Patricia Clarkson, Cam Gigandet, Lisa Kudrow, Malcolm McDowell, Aly Michalka, and Stanley Tucci.

The story is narrated by Olive Penderghast, a seventeen-year-old high school student living in Ojai, California, speaking into her webcam.

After a fight with Rhiannon, Olive decides to counteract the harassment by embracing her new reputation as a "tramp," beginning to dress more provocatively and stitching a red "A" onto her clothes, inspired by Hester Prynne from Nathaniel Hawthorne's 1850 novel The Scarlet Letter, which she has been reading in English class.

Boys who have had no previous luck with girls beg Olive to increase their popularity by letting them claim they have had sex with her, which she does in exchange for gift cards to various stores.

Olive reconnects with Todd, her childhood crush and the school mascot, who says he does not believe the rumors because she lied for him when he was not ready for his first kiss years ago.

After talking with her mother, Olive comes up with a plan – she performs a song-and-dance number at a pep rally to draw people's attention and tells them to watch her webcast that night, promising an online sex show with Todd.

Besides The Scarlet Letter, which was the source material for Easy A, Royal wanted to adapt Cyrano de Bergerac and The Mystery of Edwin Drood.

[6] According to Royal, although the word "fuck" appeared 47 times in the original draft, which was written as an R-rated comedy, all occurrences were cut from the final film.

Other songs in the film but not on the soundtrack album are from OneRepublic, Angus & Julia Stone, The Dollyrots, Death Cab for Cutie, and The Pussycat Dolls.

Blu-ray exclusive bonus features include: The Making of Easy A, The School of Pop Culture: Movies of the '80s, Vocabulary of Hilarity and a trivia track.

The site's critical consensus reads: "It owes a huge debt to older (and better) teen comedies, but Easy A proves a smart, witty showcase for its irresistibly charming star, Emma Stone.

"[16] John Griffiths from Us Weekly gave it two and a half stars out of four: "With her husky voice and fiery hair, Stone is spectacular, echoing early Lindsay Lohan...The story is thin, and the laughs meager.

[18] In a retrospective piece for The Washington Post, Anying Guo discussed its influence, pointing out how it subverted "sex-crazed tropes into a sharp, thoughtful film" by satirizing teens' obsession with virginity itself.

[19] Guo added: "Packed with references to “Say Anything” and other ’80s homages, the film felt refreshing against the steady churn of bildungsroman narratives that often centered on young men.
