On Thursday, the trailer for After was released.
The immediate hype around the film was due to its origins in One Direction fanfiction. In 2013, then-24-year-old author Anna Todd began writing After on Wattpad, a fanfic in which Harry Styles is "a rude boy..with too many tattoos and piercings," leading protagonist Tessa Young astray. And yes, there are a fair amount fanfic-appropriate sexual encounters.
Since it was published on Wattpad, the series has had hundreds of millions of views and in 2014 it was turned into a book series from Simon and Schuster. For the books, Styles' name was changed to Hardin.
Both the books and the fanfic have had a mixed response — some enjoyed them, whereas others criticized them for bad writing and unhealthy portrayal of relationships.
