A documentary of two great writers: Robert Caro and Robert Gottlieb, the film Turn Every Page is a fascinating glimpse into their work and everyday lives. Made by Gottlieb’s daughter, the movie took 10 years to come to the screen. The Power Broker author is still writing and hopes to finish the last volume of the LB Johnson biography set he began years ago. The friendship of these two brilliant men reveals how they work and how they began. A worthwhile visit to the big screen if you appreciate the intellect and subtle humor of the written word.
