Julie & Julia

Ephron's screenplay is adapted from two books: My Life in France, Child's autobiography written with Alex Prud'homme, and a memoir by Powell, Julie & Julia: 365 Days, 524 Recipes, 1 Tiny Apartment Kitchen (later retitled Julie & Julia: My Year of Cooking Dangerously). Both of these books were written and published in the same time frame (2004--06). Powell's book was based on her blog The Julie/Julia Project, where she had started documenting online her daily experiences cooking each of the 524 recipes in Child's Mastering the Art of French Cooking. The film is the first major motion picture based on a blog.
