Though there are few living who knew Keaton, Curtis has made deft use of alternative sources already published or circulating. In lesser hands, this might result in a book that treads little new ground, but Curtis breathes new life into the classic comic, exploring the richer context of Keaton’s entire career rather than merely hitting the highlights. Although ultimately celebrating Keaton, Curtis also explores, with admirable evenhandedness, the performer’s private struggles with depression, adultery, and alcoholism. Curtis does commendable work with the frustratingly necessary job of movie scene descriptions—a particularly daunting task with silent films, where one runs the risk of either bogging down the reader with superfluous detail or overlooking the qualities that endear Keaton to us in the present day.
