Back in October, Paramount bought the film rights to Anna Todd’s After, a piece of Harry Styles fanfiction that’s been read more than 1 billion times. (It’s since been published in paperback by Simon and Schuster.) Now the project has a writer: Mom’s Susan McMartin, who will be tasked with bringing the erotic adventures of Tessa, an innocent college student who doesn’t know she’s beautiful, and Hardin, her cocky tattooed British lover, to the big screen. (Sorry: If Harry Styles is famous for his hairstyle, does that mean Hardin is famous for his … ?) There’s been no word on casting yet, but we know at least one 20-something British guy with a lot of time on his hands.
