PBS, 9 & 10 p.m. ET (Check local listings) - This doubleheader of American Masters literary biographies starts with a profile of the author of Gone with the Wind, and concludes with a profile of the author of To Kill a Mockingbird. The latter is a much better book – and, as it turns out, a much better documentary, too. For a full review, see today’s Bianculli’s Blog HERE. And for an interview with American Masters creator Susan Lacy about these two shows, see Tom Brinkmoeller’s latest dispatch for his Raised on MTM column HERE.
