Roger Ebert has made an exciting announcement via Twitter: “Whoa! My memoir has been optioned for a doc by Steve James (Hoop Dreams) and Steven Zaillian, with Martin Scorsese as exec producer.” The 70-year-old Chicago Sun-Times critic’s 2011 book, Life Itself, spans his complete autobiography, from his Illinois childhood through his rise to the top of his field, struggle with alcoholism, and the thyroid cancer diagnosis that robbed him of his instantly recognizable voice. In addition to attracting heaps of praise at the time of its release — New York Times reviewer Janet Maslin named it “the best thing Mr. Ebert has ever written” — the memoir was a bestseller, and promises to make for a fascinating documentary.
