For a woman who hasn’t published a novel in over half a century — and hasn’t granted an interview in almost as long — Harper Lee is making a ton of headlines lately. A few weeks ago, after Penguin claimed Lee had cooperated on Marja Mills’ biography of the author, Lee issued a statement saying she hadn’t. Now, GalleyCat points us to the trailer for Mary McDonagh Murphy’s new documentary, Hey, Boo: Harper Lee and To Kill a Mockingbird. Although it doesn’t seem to claim Lee’s participation, and the preview doesn’t suggest it will reveal secrets about her life, the film does boast an all-star cast of Mockingbird boosters: Oprah calls the book “our national novel” in the trailer, and Anna Quindlen, Tom Brokaw, James McBride, James Patterson, and Wally Lamb all appear in the movie. Geek out after the jump.
