13 details you might have missed in 'Easy A'

King can be seen near some skateboarders outside of the school building.

In the home release commentary for "Easy A," director Will Gluck said King was there for a practical reason — to oversee the extras who were skateboarding.

Olive sings the track incessantly during an uneventful weekend at home, including while taking a shower. 

Olive's hair in the scene is a nod to Matthew Broderick's opening monologue from "Ferris Bueller's Day Off," which takes place after the titular character has successfully fooled his parents into letting him take a sick day and skip school.

While showering and explaining to the audience that he's missing a test on European socialism, Ferris puts his hair into a mohawk style. He also takes the shower head and briefly sings Wayne Newton's "Danke Schoen."

The fruit can be seen on the Penderghast's kitchen table, in Mrs. Griffith's office, and in the school cafeteria, to name a few instances. There's also a more conspicuous example of Olive meeting a classmate at an orange grove.

"We tried to put in oranges in almost every single scene of the movie because I wanted it as a motif because I didn't go to film school, so I figured I had to do something cool looking," Gluck said in the film commentary.

The Penderghast family must have an affinity for food because Olive's adoptive brother is also named Chip.

In earlier drafts of "Easy A," Olive actually had a brother named Kale and instead of Chip, she had an adoptive sister named Ginger. 

Stone's brother and his best friend, Ethan, pop up as extras in the scene when Olive and Brandon leave the bedroom after pretending to have sex. Her sibling is the guy wearing a green shirt. 

The shop is called Guillaume's of Ojai and the prop master's name is Guillaume DeLouche.

When Olive debuts her new style and new attitude at school, she flirts with Anson. 

"I just realized the funniest thing," she says. "My name is an anagram for 'I love.'"

But what she doesn't mention is that the letters of her last name can also be rearranged to spell out another phrase, "pretend shag," which is the film's major plot point. 

In the movie's commentary, Stone said that she's known Crumm since she was 11 and he's probably her oldest friend. 

Olive agrees to do favors for guys at school by spreading falsities about herself, in exchange for things like gift cards.

"Phil Lord gave me 100 bucks from Best Buy so he could tell people we hooked up behind the library," she says. 

"Chris Miller, big spender that he is, gave me $40 worth of movie passes for my pretend cowbell," Olive says. 

In the commentary, Gluck said that all the names mentioned by Olive aren't random. They're actual people that Gluck knows. 

That film is actually the 1973 German adaptation of Nathaniel Hawthorne's "The Scarlet Letter."

This time around, they're fully clothed and holding a bottle of wine and a baguette for their movie date.

Olive goes to the shop in search of a copy of the bible, which the man hilariously says can be found in the best-sellers section, next to "Twilight."

They show up near the end of the movie when Olive goes to the ice cream shop begging Evan to admit that he lied about going to second base with her.
