Charna Flam When readers and audiences hear Hello Sunshine has acquired a best-selling book, it’s likely the production company’s president of film and TV, Lauren Neustadter, has spearheaded the deal. Before joining Reese Witherspoon’s production company in 2017, Neustadter spent over a decade working in film as an executive at such companies as Miramax and 20th Century Fox, eventually transitioning to TV and serving as a Fox network exec. Once she landed at Hello Sunshine — and before she developed a slew of book-inspired series, including “Big Little Lies,” “Little Fires Everywhere” and “Truth Be Told” — she had an early book-to-screen adaptation, “Americanized,” that made it to the final stages of thenetwork development pilot cycle.
