(CNN) -- Shailene Woodley isn't just the lead actress in "The Fault In Our Stars." She's one of the book's original fans. Long before she landed the role of Hazel Grace, a bright 16-year-old facing cancer, she sent the novel's author, John Green, an impassioned, lengthy e-mail rallying for "The Fault In Our Stars" to become a movie. "I didn't say I needed to be Hazel," Woodley said at the movie's New York premiere on June 2. "I said I needed this movie to get made. Because I knew that it would change the lives of millions of people." If the movie version of "The Fault In Our Stars" is anything like the book, Woodley will soon be proven right. The adaptation, now in theaters, is faithful to its beloved source material, which chronicles the romance between two cancer patients with humor, intelligence and honesty. Author Green had already amassed a fan base when "The Fault In Our Stars" was released as a novel in January 2012, one devoted enough to earn him the title of "The Teen Whisperer."
