Much like “Fifty Shades of Grey” arose from “Twilight” fanfiction, Anna Todd’s novel was originally a Harry Styles fan fiction story on Wattpad which became an original work and now a teen-targeted film. Josephine Langford and Hero Fiennes-Tiffin star in the story of a dedicated student who meets a magnetic, brooding rebel who makes her question all she thought she knew about herself. Jenny Gage directs the film which is being popped out in April.
