Have you noticed the recent uptick in little girls named Harper and little boys named Atticus? First of all, those kids are going to have a rough time finding personalized license plates for their bikes. Second of all, it’s pretty clear that “To Kill a Mockingbird” had a profound effect on a lot of people. Now, you can get the inside story of author Harper Lee, who once said she wanted to be the “Jane Austen of South Alabama” yet wrote only one book and then vanished, never publishing again. Director Mary Murphy’s new documentary, “Hey, Boo,” uses photos, letters and interviews — including one with Lee’s sister, Alice Finch Lee (Finch! Like in the book!) — to explore the mysteries surrounding the author of one of the most important books of the 20th century. There are, unfortunately, no interviews with Lee herself (yes, she’s still alive), but celebrities such as Oprah Winfrey and Tom Brokaw talk about what the book means to them.
