According to Hollywood Elsewhere, Portman and college friend Laura Moses's screenplay - billed as a female-themed Superbad - has an early scene where one of the lead characters, Lucy - described as a "wild sex fiend" - gets caught having oral sex by the underage boy's mother.
However, a source who read the script played down the raunchy content, saying that it is more focused on "Michael Cera snarkiness and McLovin dopey-ness”.
"It doesn’t get any dirtier than the page five BJ," the insider is quoted as saying. "I can see it being funnier acted out. It just seems lurid because it's about chicks acting like horny dudes."
Portman is on board to play the lead in BYO ('Bring Your Own'), about two twentysomething women who throw a party where their friends must bring one eligible bachelor, while Anne Hathaway is said to be interested in taking on the other role.
Portman and Moses are currently pitching the BYO script to Hollywood studios.
