Film critic Roger Ebert is writing a memoir, according to a new report from the AP.

The untitled book will reportedly touch upon numerous subjects in Ebert's life, including his recent battle with thyroid cancer, which rendered him speechless, and his friendship with longtime TV cohort Gene Siskel, who died in 1999 at age 53.

Grand Central Publishing will release the book, with a tentative launch date for fall 2011, according to executive editor Mitch Hoffman.
