Malina Saval Associate Editor, Features In the late 1990s, after teaching herself screenplay structure by way of reading Viki King’s seminal go-to manual “How to Write a Movie in 21 Days,” Andrea Berloff emerged with her first feature script titled “Liberty,” a comedy set in a small-town Ohio dart tournament. “I had no idea at that point that there were three acts in a movie — I’d never had a class in it,” says Berloff, who cut her teeth as a theater major at Cornell U., poring over Greek tragedies and Shakespeare’s dramas. And while “very few people read that script,” the friends who gave “Liberty” a look served as “encouragement to keep writing,” says Berloff, who would go on to option her second, the biopic “Harry and Caresse” to Fine Line (the then-specialty division of New Line) in 2003, pen the Oliver Stone drama “World Trade Center” and net an Academy Award nomination for co-writ- ing, with Jonathan Herman, the 2015 N.W.A origin story “Straight Outta Compton.”
