TURN EVERY PAGE explores the remarkable 50-year relationship between two literary legends, writer Robert Caro and his longtime editor Robert Gottlieb. Now 86, Caro is working to complete the final volume of his masterwork; Gottlieb, 91, waits to edit it. The task of finishing their life’s work looms before them. With humor and insight (a vigorous debate over Caro’s use of semicolons is a hilarious highlight), this unique double portrait reveals the peculiarities and professional joys of these two ferocious intellects at the culmination of their spectacular, shared journey. PG-13, 112 min.
