International best-selling author Nicholas Sparks sat down with us recently to talk about Dear John, the latest film to be adapted from one of his novels. Directed by Oscar nominee Lasse Hallström, Dear John tells the story of John Tyree (Channing Tatum), a young soldier home on leave, and Savannah Curtis (Amanda Seyfried), the idealistic college student he falls in love with during her spring vacation. The film also stars Oscar nominee Richard Jenkins.

Sparks, who currently resides in North Carolina with his wife and five children, has published fifteen novels of which six have been turned into films. They include The Notebook, Message in a Bottle, A Walk to Remember, The Last Song, Dear John, and Nights in Rodanthe. Sparks also wrote the screenplay for the film adaptation of his novel, The Last Song.
